What I pull from that is that the error causing the problem is a page
fault when it asks for some memory.  But I don't know where to go from
that insight, other than opening a bugzilla against the kernel,
describing your problem, and attaching your screenshot with its stack
trace. I'm stumped. If it boots from USB, then the memory must be
working properly, but here you are failing when accessing memory.
What's different?

Long shot, reseat the memory, and run a memory check, to be sure memory
is OK.

Too bad.  I see that Tony gave you a workaround.  That will show
the state before the error, but not after the error.  I vaguely recall
that there is a way to tell the kernel or systemd to dump a core file
when this happens.  That would also be good to attach to a bugzilla, if
it is available.
