Symptoms

When the game starts the cursor changes to the blue ingame cursor but the screen remains black, you can hear the start up game sounds but nothing happens after that. If you alt tab and then tab back you can sometimes see a frozen frame from the intro animation. (see below picture)

Reproduction

Just select proton 9.0-4 and start the game, this didn't happen before, it used to take 30 seconds to start and then the game ran fine, i'm not sure which proton version it previously worked with. I tried many different versions now but all of them have the same issue.
