Hi, achiestdragon
Thx for all the research you have done.
I dont know about the setup on Linux, but, it seem normal that you need vulkan on this platform.
I hope the driver update help you, cross finger for your new graphic card.
On Windows Unreal run with directx 11 and/or 12 on modern graphic card which is the case for mine.
The driver is up to date as always and my computer over meet the recommended spec.
As mention in my post i have build Unreal (5.0 and 5.1) from source several time in the last year and never get this error before.
I do not know if some one from Epic team can jump on this to clarify this case ?
