Are there other reports for Python 3.11 too? E.g. with Fedora 37 or Archlinux?
More detailed research in LE requires using a debug image.
There's been reports for Android but not so much other Linux.
EDIT: Just had someone report same issue on Ubuntu 22, so not limited to LibreELEC. Reported the issue on xbmc github since the issue seems to be platform agnostic: https://github.com/xbmc/xbmc/issues/22344
However, it seems to occur more frequently on ARM chipsets and not so much on x64, which would explain fewer reports on "normal" distros. Running Generic-Legacy LibreELEC in a VirtualBox VM on my laptop (Intel i7) I've been able to make the issue occur twice but it seems relatively difficult compared to the reports I'm getting from ARM users.
I've got a couple of users who can reliably reproduce the issue on ARM devices as soon as we enable the API which parses XML data via ElementTree. See specifically this comment (first issue was addressed but second one is the ElementTree issue) https://github.com/jurialmunkey/p…ment-1364672534
And here's the two crash logs from my VM with backtrace showing elementtree thread segfaulting.
