Hello,
I tried to reproduce the issue again today. Although this time the
installer didn't crash ("$ vgs" and "$ lvs" returned valid information),
I was in a scenario somewhat similar to what I described in comment 29:
$ dmesg

Could you check if you're seeing any of the above errors? Ideally, would
you mind sharing the journal logs + dmesg.log?
Thank you,
