Failed to load Vulkan Driver - Unreal Engine 5 (LINUX*ubuntu*)

Development Getting Started & Setup

I’m having the same isssue on Fedora 42. I tried running 5.5.3.
what weirdly got me past the loading was actually creating a project using the First Person Blueprint template. All the other templates I’ve tried would fail. with the ‘Failed to load Vulkan Driver’ error.

Copying the DefaultEngine.ini file over from the First Person template project to another one, fixed it. although I can’t spot anything obvious in that config file.

I’m running an integrated intel Iris Xe (driver 25.1.4).

EDIT: actually, the “SF_VULKAN_SM5" worked but it has to be in the Project’s DefaultEngine.ini instead of DefaultEditor.ini (which was my mistake). the full content is:
