Occasionally you may come across an issue when one of your apps is stuck uninstalling on your headset and nothing seems to work even if you restart your headset. Factory resetting used to be the solution, but don’t do that! Instead, go to SideQuest, click on “installed apps”, then "Show All", find the app called "com.oculus.ocms", then go to its settings and click "Clear app data". And as simply as that, you avoided the dreaded factory reset and solved the problem of a stuck app!
