Symptoms
The game crashes (coredumps) when intro vidoes are supposed to play.
Renaming/moving the intro videos makes the game start.
Using PROTON_ENABLE_MEDIACONV=1 %command% does not help.
I also recreated the prefix using Proton 11 because proton-cachyos-slr failed to do it (EAApp issue), but that did not help either.

Steps to reproduce
- Just launch the game with cachyos-proton-slr, it should load but crash when the intro video is supposed to show up
(launching the game with proton 11 shows the color bars and game works)
