First time Linux-gaming, trying to play an installed game

Hey all, I've recently installed CachyOS and I linked my Epic Games account to Heroic.
However, since it's my first time, after installing a game not native to Linux (S.T.A.L.K.E.R.: Shadow of Chornobyl - Enhanced Edition) and trying to play it - it does not start.
How do you configure Windows games for Linux in Heroic?
I've attached the logs from the game if that helps.
Thanks in advance!

Proton-CachyOS's non-runtime version (the one you're using right now) won't work in umu. Install the "slr" (Steam Linux Runtime) version instead, or just use another Proton fork (e.g. GE-Proton)

Seems to work now (except playing pre-rendered videos, but I can live with that) - thank you!

Hm, they're certainly supposed to work with GE-Proton. If you want to look into that, send in another game log

Alright, here are the log and what I see when opening the game - the credits cinemtaics are off-color and divided to 4 somehow.

now this works for Steam copies but not sure it would do for GOG one.
