Kernel Panic 14.0-BETA2

I have a 14-CURRENT snapshot running, which is from the end of may.

FreeBSD 14.0-CURRENT #0 main-n263139-baef3a5b585f: Thu May 25 08:14:14 UTC 2023

I would like to update the VM to releng/14.0, but when I boot a recent kernel
vom releng/14.0 I get a kernel panic. See the attached screenshot.

The strange thing is that a snapshot for BETA2 boots without problems.

Does any has a clue what's going on?

I could setup a new BETA2 based 14.0, but I would rather prefer an update.

Any help is very appreciated.
