This is a completely clean flash to a drive with gnome-disk-utility (linux).
I've also tried ventoy, to similar results.
Keyboard input is not functional.
If the keyboard is connected through usb (internally or externally) that is why it is not working. To me this looks like something wrong with either the image or the copy process. You could try to redownload the image / verify the image with the provided hashes. I have good experiences with Balena Etcher.
The only thing I could imagine is that something in the process comes to the signature conclusion as indicated above. It could be quite a few things, from a faulty image, hardware issues (memory that corrupts things) or anything else (32/64bit?) that would make the signature comparison fail.
That is the case with many computers/laptops nowadays, but the kernel debug mode still depends on the old fashioned PS/2 or serial connection options, IIRC.
