I tested with and without the 1.1 update, installed via WINEPREFIX=/srv/games/Linux/SteamLibrary/steamapps/compatdata/1490410/pfx wine /srv/games/Linux/update.exe

(If you use that command, make sure you've got the equivalent Wine version installed, use the actual path of your Steam library and rename the patcher to update.exe to avoid spaces in filenames)

I tried this with regular Proton 7.0.4 and GE-Proton7-48, both with the Game.exe from Steam and the Game.exe produced by the 1.1 update patch.

In all cases, the game takes several minutes to load, spawns 5 Game.exe processes (of which 2 disappear after a while), but then only displays an empty black window.
