Installing d3dcompiler_47 to the wine prefix will probably fix it. HLSL compilation is not handled by vkd3d-proton, this is a wine bug.

I have already installed d3dcompiler_47

thanks, I'll report to wine then

If it's not _47 it might be some other version, this seems to be an old game. You can check the version it loads with WINEDEBUG=+loaddll
