According to logs with 4.11-2 it's using WPF:
1644834.345:003a:003b:trace:mscoree:mono_assembly_preload_hook_fn "PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Can't find custom attr constructor image: data-03D32E58 mtoken: 0x0a000010 due to: Could not load file or assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
[0000003B:] EXCEPTION handling: System.IO.FileNotFoundException: Could not load file or assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
I also get dxvk error for texture creation failure but it might be unrelated.
@bastafidli This launch failure should be fixed on 6.3-1. Please retest :)
