I was able to disable mode switch and record a video with the kernel attempting 
to output the oops.
It seems to be an issue with apparmor.

The text I manually recovered from the video:

I will also attach screenshots from the video

Title:
  NUC12WSHi7 hangs few minutes after boot with linux-
  image-6.5.0-14-generic (linux-image-generic-hwe-22.04)

Status in linux-hwe-6.5 package in Ubuntu:
  New

Bug description:
  Today one of my NUCs got new kernel 6.5.0-14 and the host started to hang few 
minutes after the boot.
  I can't find anything in the journal for the previous boot it just ends 
without any error. Remote syslog server does not receive any error log from 
this host. I've tried running journalctl on the local console and wait for the 
hang got nothing.
  On the screen (this is Ubuntu Server) I see 18 hex numbers at the top of the 
screen and the rest is what was on the console before the hang:
   ff ff 73 01 c3 48 8b 0d 74 ed 12 00 f7 d8 64 89 01 48

  Booting the previous HWE linux-image-6.2.0-39-generic fixes the issue,
  so it is definitely the new kernel.

  I don't have enough time to generate report with ubuntu-bug on the new
  kernel, so attaching dmidecode, lspci, lsusb and dmesg from the older
  one.
