I tried to launch a game from Heroic on the Deck for the first time in a month or so and it’s loading for a few seconds and then exiting.

  • Same from game mode or desktop
  • Same for different proton versions
  • Same for Epic, GOG, and Amazon games
  • Same after reinstalling a game
  • Other Steam and non-Steam games run fine

I’ve probably applied several updates since I last ran a game so no doubt a huge number of things have changed since the last good state. I can’t see anyone else reporting similar issues so I know it’s very optimistic from me, but does anyone have any suggestions? Even an idea of how to get some logs out would be useful!
