The Witcher 3 is not loading textures (and sound)

I just installed The Witcher 3 on my steam-deck's SD card and I'm launching it using Wine-GE-Proton8-26but whenever I log into the game, there is a huge issue with texture and sound loading (see picture). Interestingly enough, this issue is not happening on the title screen page where both sound and image are ok. I tried using other Proton versions, running with the DX11 launch option and I used the Verify and repair tool but none of this changed anything.

Here is the log file.
