Adding some information that might be useful: the game is built with net8.0-windows and /p:PublishSingleFile=true /p:SelfContained=true. Which seems to be the issue with current proton version used in Steam
Fixed in a recent Proton Experimental update

Fix/Workaround
Wine-master works flawlessly, so to run it in Steam, I obtained a build of Proton which uses it.
For reference, I used Proton-TKG built with wine-master (proton_tkg_9.17.r8.g1baaa8fb)
I'm not sure of the exact commit in wine-master which fixes this.
