ROMs don’t boot on Quest 2

Hello,

I recently got a quest 2 and just installed dolphin. my ROMs show up in the game list, and I got it to boot once. When I entered “theater mode“ to make it full screen, the screen turned black. Since then, whenever I try and run any of my games, it just stays on the game select screen. This is running the Android version. Any help/explanations/troubleshooting would be appreciated!
