Despite the look of it, the error message has nothing to do with a website or web page for your Quest or Quest 2. To understand its causes and how to fix it, you first need to understand the origin of the “com.oculus.guardian keeps stopping” error message. Please read on for details.
What Does com.oculus.guardian Mean
Com.oculus.guardian is essentially the public name of the software that makes Oculus Guardian to work on Quest and Quest 2. That is, it is the part of the Guardian software programme that is visible to users. Software programmes can develop glitches and bugs from time to time making them to stop functioning properly. When the Guardian software programme stops working, it displays the “com.oculus.guardian keeps stopping” error.
Why is This Important?
Oculus Guardian is the feature on Quest and Quest 2 that keeps you safe in your physical playing area. It allows you to define boundaries within your playing space to stop you from walking into objects while using Oculus. It displays wall and floor markers when you move close to the boundary you have defined. You may also be aware that in 2021, Oculus introduced the Couch Mode feature in Guardian which allows you to mark your actual couch in your playing area so that you can sit on the couch and continue playing instead of the couch serving as a boundary. All these features are compiled as “com.oculus.guardian”. This “com.oculus.guardian” is also made available to developers to add features to the Oculus Guardian system. Developers were responsible for adding features like Space Sense or Intrusion Detection (which allows you to see people and pets entering your playing space. Therefore, when this compiled code runs into an error, the entire Guardian system stops working, returning the “com.oculus.guardian keeps stopping” error.
Why Does Oculus Say com.oculus.guardian Keeps Stopping
Now that you understand what com.oculus.guardian means, and why it is important, let’s take a look at the known causes and explore how to avoid them.
1. Out-Of-Date Oculus
The first reason why Guardian, or more accurately, the software that controls Guardian on your Quest or Quest 2 may run into such error is because your Oculus is out of date. Oculus rolls out key updates periodically that add new features and functions, and improve performance of your Quest and Quest 2 headset. These updates are meant to provide your Oculus with the ability to support the latest virtual reality titles and games. So, when your Quest or Quest 2 is out of date, many functions stop to function when you try to access latest apps. And, the Guardian system is one of those functions that rely heavily on updates in order to continue supporting the latest VR title and games you use. You may also be aware that Oculus Quest (1) has been discontinued by Meta. Although it still receives updates, it does not receive all the features that the Quest 2 receives. That’s probably the reason why the “com.oculus.guardian keeps stopping” error is reported more among Quest 1 users.
2. Newly-updated Oculus
The flip side of the fact that an out-of-date Oculus can cause the “com.oculus.guardian keeps stopping” error, is that a newly-installed update can also cause the Guardian software to stop working. In fact, this happened with many Quest devices after the v39 update. However, Oculus usually release updates fixes to rectify this problem.
3. Guardian Cache or Oculus Storage is Full
Every time you set a Guardian Boundary for a game, the information is saved as Guardian History, and in a temporary memory called a Cache. Almost all smart devices have a cache, including your phone, PC, and smart TV. The highest storage on an Oculus is 256GB, and only a little fraction of this is assigned for Guardian cache. So, when you have many Guardian Boundary settings on your Quest or Quest 2, they may fill up the cache causing the software to stop processing new data. This results in the “com.oculus.guardian keeps stopping” error. The amount of cache memory available on your Quest or Quest depends directly on the total storage of your device. So, the more games you have, and the more boundaries you set up, the less cache space available for Guardian to run optimally.
4. Issues with Tracking
For Guardian settings to work, your Quest or Quest 2 has to capture and record your playing area, as well as your movements in your playing area. The feature on Oculus that performs this function is called Tracking. Tracking works very closely with Guardian to track your movement within your playing area and then alert you when you move close to the edge. Because of this dependency of Guardian on Tracking, an issue with the Tracking system will cause Guardian to stop working, resulting in the “com.oculus.guardian keeps stopping” error. That’s why, many a time, resolving an issue with Tracking automatically resolves the error on Guardian. Some of the factors that cause issues with Tracking include:
New Software Update Out-of-date software Reflective items in the playing area Dark playing area Too-bright or overpowering playing area
How to Fix ‘com.oculus.guardian’ Keeps Stopping” Error
We have explained that com.oculus.guardian is the compiled code that controls the Guardian system in Oculus. To know the exact cause of the error each time it occurs, you would have to have access to that code. This is why resolving the “com.oculus.guardian keeps stopping” is done by the user using a trial-and-error approach. We have provided a list of known fixes that resolve the error below:
1. Update Oculus
One of the main reasons why you keep getting the “com.oculus.guardian keeps stopping” is that your Quest or Quest 2 is out of date. Oculus is normally set to update automatically.

2. Perform A Clean Reboot
There are many types of restarts on Quest and Quest 2, and each of them serves different functions. The key types are:
Simple restart Hard Reboot Clean Reboot Bootloader Reboot
We have covered most of these in other articles. A clean reboot essentially forces your Quest or Quest 2 to restart without loading any extra functions such as when you have enabled Sideloading Updates. Performing a clean reboot, therefore, cleans out any bugs and settings that may be causing Guardian to stop working. To perform a clean reboot:
- Press the power and volume down at the same time for about 30 seconds
- Once the boot menu loads, use the volume control keys to highlight Exit and Boot
- Press the Power button to select and reboot the headset After the headset restarts, try to play a game and see if the “com.oculus.guardian keeps stopping” has cleared.
3. Cover All 4 Cameras For A Few Seconds
Remember that the Guardian system integrates with Tracking to track your movement and warn you when you get close to the edge of your boundary. And remember that we explained that an issue with Tracking will cause an issue with Guardian, too. Well, Tracking uses the cameras to capture your movement in your playing area. Sometimes, due to a bug in Tracking or if the playing area is too bright, Tracking camera will stop working and cause the “com.oculus.guardian keeps stopping” error to occur. To test, when the error occurs, use your hand to cover all 4 cameras for a few seconds and see if the error clears.
4. Change Tracking Frequency to 50HZ or 60HZ
On Oculus, Tracking Frequency is the frequency at which your Quest or Quest 2 compares your current location to the previous. It is measured in cycles per second. The default frequency setting is usually Automatic. However, setting a higher Tracking frequency will improve the performance of Tracking and in turn, that of Guardian. To increase tracking frequency:
- Press the Oculus button on the right controller
- On the Universal menu, select Settings
- Select Device
- At Tracking Frequency, select 50HZ or 60HZ Please restart the headset after this and see if the “com.oculus.guardian keeps stopping” clears.
5. Clear Cache/History and Clear Storage
In the previous section, we explained the relationship between your Quest or Quest 2 storage and Guardian cache. And, we showed how both of them affect the performance of Guardian. To clear the “com.oculus.guardian keeps stopping” error, therefore, you need to clear the Guardian cache and free up storage in your Oculus. To clear Guardian history/cache:
- Press the Oculus button on the right controller

8. Replace Poor-quality Touch Controller Batteries
Guardian integrated with Tracking is a very powerful technology and requires sufficient power to work well. Apart from your headset battery, the batteries on your controllers are very important for the functioning of Guardian. Even if your Quest or Quest 2 is fully charged, the quality of the power supply from the controllers may cause Guardian to malfunction and return the “com.oculus.guardian keeps stopping” error. If you are using rechargeable batteries, you may be best served by high-quality Alkaline AA batteries instead for your controllers. Then observe to see if the error clears.
9. Turn The Headset Off, Charge The Headset, Then Turn It Back On While Keeping It Charged
Still on power supply, your headset battery may not have enough charge, or the quality of your headset battery may deteriorate over time making it unable to sustain the functionality of Guardian. To test for this:

- After a while, turn it back on while leaving it plugged in
- Use the headset to see if the “com.oculus.guardian keeps stopping” error has cleared.
