Actually, I am certain that the behaviour was triggered *by the copying
process*, as the log journal entries were reproducible by repeating the
installation for a second time.

The logs indicate some *failed attempts* to SIGABRT and then SIGKILL.
Shortly after the completion of the operation (when the kernel emits sda:
sda1 sda2), a log:

systemd-udevd.service: Main process exited, code=killed, status=9/KILL

can be spotted. Thus it is rather clear that the error is truly related to
the ISO image installation to sda.

Possibly the USB stick leads to such a kind of lock-up as you mentioned,
while the copying process is underway? The actual *copying procedure*
completed successfully.

Hm, what should I look for?

Best,
