Hello @r3animate, does other games on /run/media/reanimate/data/SteamLibrary work? err:virtual:map_image_into_view failed to set 60000020 protection on L"\\??\\C:\\windows\\system32\\d3d11.dll" section .text, noexec filesystem? hints there's a general issue with how the partition which the game (or potentially Proton 11) is on is mounted.

Shoot -- that's absolutely it. Thank you @kisak-valve -- brand new library on that drive / I moved it to the main drive and it tested fine on Proton Experimental. I'll close this and go sort my permissions issues ;).
