Symptoms

Game has a start screen (Autorun.exe), which starts upon launching the game in Steam.
Clicking on 'Start' however does not launch the game, it stays at the start screen.
Launching the game manually via the command line leads to a game related error message, complaining that it cannot be run outside of Steam.
Tried installing corefonts dotnet40 with winetricks, to no avail.

Logfile

steam-321410.log

Start with the linked steam-321410.log and the reported Autorun.exe launch flow, then reproduce the game launch through Steam using Proton 3.7-6. Compare it with the command-line behavior described in the report. Done means identifying a confirmed cause and working Steam launch path, or documenting why the compatibility issue remains unresolved.
