If you are using lutris , try to use kron4ek's wine (you can install it with protonupqt), i found out it tends to work better with repacks, then when it's installed switch back to what you were using.
I might have got it. Wine/Proton doesn't like nfts partitions which is what windows uses. symlink your game folder into a brfts or ext4 partition, like your home directory and try to launch the game using that path like home/username/Games. point launchers to this path whatever ur using steam lutris heroic etc
