Sometimes, Beat Saber just won’t behave. You need to forcibly uninstall it.
SideQuest will help you do this. You probably already have it installed. If not, you’ll need to setup SideQuest.
- Plug your Quest into your PC and run SideQuest.
- Click the 9 pip icon in the top bar of SideQuest

- Search for Beat Saber (you can also use the Search box and type in beat to filter)
- Click the gear icon next to that package
- Select UNINSTALL APP
- Click CLOSE

If you’re looking to start from scratch, please Uninstall BMBF also.
