This is a bug in Wine's d3dcompiler implementation which is known to be broken with DXVK
Please install native versions of this lib in winetricks/protontricks and see if it helps your problem.
Looks like it's trying to query ID3D11Predicate from something that isn't a predicate?
Now that I look at the mentioned issue again, you were probably asking for a dxvk apitrace for the d3dcompiler:d3dcompiler_shader_reflection_GetDesc errors. Luckly I have some of those in my log, too
If you don't see anything in the log that can be fixed by you, feel free to close the issue. I'm just fishing for errors
d3dcompiler is not part of DXVK. Just install the native library with winetricks d3dcompiler_43 d3dcompiler_47 and try again.

I was actually trying to diagnose an unrelated issue pertaining to jerky camera movement (maybe performance related?) when I came across these errors. Truthfully, I'm not sure what visual problems these errors are causing because I haven't been able to play the game on Windows yet to compare.
There's 2 different sets of errors I'm seeing:
And to a lesser extent:
Looking at #1200 I saw that an apitrace while using DXVK helped you last time. I have linked one for you below.
