Using Proton 8.0-4, I was unable to reach the main menu. I launch the game and see the Bethesda logo, which does not go away and seems to be frozen. The Steam pop-up that appears in the bottom right is also frozen. However, I do hear the music as if I was in the main menu as normal. The game works fine when I change to Proton 7.0-6, but a tool that I wish to use wishes for me to use Proton 8.0.
