The game launches for me and I'm able to get into gameplay without issues on my setup, tried both DX11 and DX12.
Screenshot of game running:

Tested Bleeding Edge Experimental, Proton RC and default Proton.
Logs of successfull test runs:
steam-1567020- proton-7.0-4.log

Integrity of game files successfully validated but the game still crash.

I'll tell you how to reproduce the problem.
I expected that all removed files on step 3 would be reinstalled. But something gone wrong.
Workaround - verify integrity of stable proton 7.0.4 and relaunch game with stable proton.
"Proton Hotfix" is also affected by this issue.
