If you run PSUnreal inside a terminal emulator with scrollbar, you should be able to scroll up to read the text.
Do you have Vulkan driver support installed? In Debian/Devuan/Ubuntu its supposed to be in the package mesa-vulkan-drivers. Also Intel Xe graphics is quite new. Maybe Ubuntu 22.04 is too old? In package vulkan-tools is a command named vulkaninfo.
Under Layers this command should display the found graphics drivers. There should be at least one layer which relates to your graphics chip (Intel Xe graphics). I for example have something like:
Layers: count = 3
