My game is no longer running on Steam Deck (Linux)

I've downloaded the Sims through the Steam Store. It's now doing this thing where the EA App loading window opens, closes, then it shows in my library that the game is no longer running.

I've backed up my Documents>Electronic Arts folder, then tried:

• deleting proton, verifying file integrity then running.
• using this protontricks tutorial: link.
• uninstalling the game, reinstalling, then running the fresh install.
