In short:

• I start the game
• I choose continue or new game
• The game is loading
• The loading bar is almost full and then I get this message: "Unfortunately the game has crashed. Do you want to help us fix the issue by sending a crash report?"

What I have done so far:

• I have disabled DLSS
• I have tested various launch options recommended here from other users
• I have also tested with the following proton versions: hotfix, experimental, 9.0-4 and 8.0-5
