The answer is one dll that gets loaded that causes the game to crash on startup. Go to $WINEPREFIX/drive_c/GOG Games/Cyberpunk 2077/bin/x86/ and rename GameServicesGOG.dll to GameServicesGOG.dll.bak (or delete it if you like to live life on the wild side). Now enjoy playing the update!
This was tested on Arch using AMD and latest mesa.
It tries to communicate with galaxy to verify you own the dlc. So with this fix you can’t play the dlc using heroic. Unless you use comment or galaxy in wine.
…so it’s DRM? Isn’t GOG explicitly no DRM?
Yes it’s drm, and that is the debate I’ve seen around. Some are saying gog is going towards drm and some say they are already there.
Oof. Ok, thx for the context.
