Tried on proton-experimental, proton-6.1-GE-2 and Wine-6.2
Installing d3d12.dll in the game folder (Cyberpunk 2077/bin/x64, next to the Cyberpunk2077.exe) makes the game hang after about a second from launching. You can hear the intro music start to play and MangoHud shows up. You can see by the timeframe histogram that it started and froze shortly after.

EDIT: Doesn't hang up with mesa-git
