Problems launching with Proton-GE

This could just be a game specific issue because of a point I’ll make at the end but thought it was worth asking.

I was trying to play Lego Lord of the Rings and saw that the horrible visual glitches could be fixed by forcing Proton-GE. I installed proton ge and selected it for the game, and then the game wouldn’t launch.

I then tried another game with proton ge and it launched like normal, so I really don’t know. My question is mainly because lots of steam deck users say proton ge “just works” for this game whereas mine doesn’t launch at all.
