Kernel null pointer dereference when encoding video?

Ah okay, no clue why, but there is a mismatch in comparison to the current microcode revision but it doesn’t seem to be related as I’ve got a different CPU model.

Anyway:

Machine:
  Type: Desktop Mobo: ASRock model: X570 Taichi serial: <superuser required>
    UEFI: American Megatrends v: P4.80 date: 02/16/2022

You’ve got the latest microcode. But the BIOS you’re using seems to be quite old.
