Proton Experimental updated to get Crimson Desert working again on Linux / SteamOS

A recent update to Crimson Desert has been causing problems on Linux / SteamOS with it not launching, so Valve patched Proton Experimental to fix it.

Crimson Desert should have Proton Experimental as the default Proton version, so you shouldn't need to do anything. But, you can also force a specific Proton version on a game in the Properties -> Compatibility menu in Steam.

Valve only just recently updated Proton Hotfix for HELLDIVERS 2, so they're busy putting out fires from multiple developers launching updates with issues. On top of that there was also the recent update for both Proton 11 Beta and Proton Experimental to fix the EA App (again!).

The April 29th update for Proton Experimental didn't just fix Crimson Desert, as Valve also noted that "Plain Sight" is also now playable.
