Libreshop: Lock screen and logout both work normally. Reboot causes the
same problem as shut down.
loldier: Pressing esc did exactly what you said it would!
I did this several times and each time this is what I got each time (except
once, see below).
[ OK ] Started Show Plymouth Reboot Screen.
[ OK ] Stopped Cryptography Setup for nvme01p5_crypt.
[ OK ] Reached target Unmount All Filesystems.
[ OK ] Removed slice system-systemd\x2dcryptsetup.slice.
[ OK ] Reached target Shutdown.
And then on the line below that is a flashing cursor (like a flashing
underscore character). It stays there forever.
But one time I got this instead:
[ OK ] Started Show Plymouth Reboot Screen.
[ OK ] Stopped Cryptography Setup for nvme01p5_crypt.
[ OK ] Reached target Unmount All Filesystems.
[ OK ] Removed slice system-systemd\x2dcryptsetup.slice.
[ OK ] Reached target Shutdown.

I haven't been able to figure out why I got a different result just one time.
I feel a little closer to a solution, now that I can at least see something
of what's happening. Perhaps this text means more to someone than it does to
me?
Thank you so much everyone who has posted suggestions.
