Maybe check your drives for errors.
I had this EFI problem and it turned out to be a couple of file system errors on one of my old windows HDD’s I use for data (not the W11 system drive). I read it somewhere on internet this could be the problem. I think after doing the scannow thing and catching errors on Windows 11, Bazzite installed fine on a clean formatted SSD after.
Bazzite seems to be picky on disk errors, unlike Windows, Windows reported it as totally fine until I checked manually.
Just to make sure I disconnected the data drive, Bazzite installed without any effort (or errors).






And on Bazzite too.
I have the 8bitdo 2c with PC dongle. The only game I had issues with is No Mans Sky, but those problems do occur on Windows as well. I like them better than my Xbox controllers.
