Symptoms

The book animates and opens but you can see that it gets inverted before it opens. Then the game is just stuck in that screen. Audio still plays but any input won't do anything. Only way to exit is to force exit the game via menu.
This issue happens in Proton 10 and above. By forcing Proton 9 or below, the game works totally fine.

Reproduction

  1. Open the game
  2. Start a new game
  3. Or Select Chapters
  4. Or Select Toys
