On <Cntrl><Alt><Delete> from there, still stuck in that loop. It displays an error message just before the BIOS Boot menu, but flashes by too fast to actually make out what is there. If it shutdown, and cold boot, it boots normally to the Grub2 Boot menu. There is a problem somewhere. This machine is ZFS-On-Root. Another User says he is having this same problem, but on an LVM2 install. The common denominator seems to be the update to Linux kernel 6.2.0-26.
