I have exactly the same problem with Miscreated (ID 299740). I think it could be pretty much related.
I want to revive this issue because I have new information on this game.
The game is playable now, but there's a constant lightning flickering that may cause severe eye strain. This issue is demonstrated in the following video:

There's also something weird in the Main Menu screen, I don't think it should be shown like this but I don't have anything to compare to since I don't know how the native version behaves.

Just start the game normally and start playing.
The lighting issue is seemingly random. Sometimes you don't notice it and other times is it very severe.
Probably related to the flickering problem in MGSV.

The Game Crashes when it get's to the title screen and the animated graphic doesn't load so i think it's something to do with that
You just get to the title screen with Proton 10 and above and it'll shortly crash
Hello @flying-night-slasher, please note the newest Proton version you tested that had the game running as expected.

For me it "works" until I get to the title screen. It works on Proton 9 but Proton 10 and above crashes it. I could record it crashing if you want.
@kisak-valve I tried it on the newly released Proton 10.0-4 and it still crashes so should I give a new log and system report for that version?
