Thank you for taking the time to report this bug and helping to make Ubuntu better.

If GNOME-shell suffers from a crash, all programs are killed & the user is logged out. There can be many reasons for this, however it's not related to the `ubuntu-release-upgrader` package which upgrades a release (from focal/20.04 to groovy/20.10 for example)

I'm not sure what package this should be filed against, I see only evidence of i915/graphic crash, but little detail is available (partially as filed against the upgrade tool).
