Installing d3dcompiler_43 and d3dcompiler_47 via protontricks seems to make it run. Note that I have not verified whether both are required for successful operation.
I was able to play through the entire campaign, except for a crash in mission 9 in the elevator, which I fixed by disabling vsync and changing from fullscreen to windowed.
Game still seems to get stuck on a black screen on launch on steam deck using proton Experimental unless you use protontricks to install d3dcompiler_43 and d3dcompiler_47

Hello @waspennator, these look like some lines of interest from your log:
err:d3dcompiler:D3DCompile2 Failed to compile shader, vkd3d result -4.

https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/115 might help with that.

No proton version tested works out of the box.
As this fix is merged for quite some time, I don't think it helped with this issue.
The only fix is still to install d3dcompiler_47. I tested it with success, even without d3dcompiler_43.
It runs perfectly fine on my Steam Deck.

PR has been merged for quite awhile, I don't think that changed anything, still get a blackscreen like mentioned above on my oled deck using experimental unless you use the protonfix.
Should I provide another log file?

Is this build of vkd3d in proton yet?
Edit: Nevermind, accidentally thought this was merged in earlier, but it seems like it was pretty recent.
Build seems to have finally hit proton Experimental and i can finally play through the game on my oled deck.
I have tested a few times since @waspennator posted last comment and can confirm that the game launches and plays without issue.
I confirm this game is now playable with Proton 10.0 without workarounds
