Constant KP on Big Sur-installation attempt (OC), ASRock Z390 Phantom Gaming ITX/ac, 9700K, Samsung EVO 970 NVMe

There's a very long halt at validating_root_image and after yet another long period of time I get a Kernel Panic (NMPI for unresponsive processor). I've linked screenshots from these points. I can also see several AppleNVMe assert failed flashing by which reminded me that there were som issues with earlier firmwares of the EVO 970-drive. This drive is a recent one though so I think the fw should be the latest.

There's also s WD Blue SN550 500GB in the 2nd M2-slot which may mess things up but it isn't initilized yet.

The EFI-folder can be seen here (for inspection only. Do not use!):

I found a suggestion to set ReleaseUsbOwnership to TRUE in this reddit-thread here. I'll test that.

Am I missing something obvious?
