Additional info
The fix is just to move the code of the app at the right place:
mv /path/to/nextcloud/apps/calendar/ $HOME/calendar
mv $/HOME/calendar/calendar /path/to/nextcloud/apps/calendar
It's a Nextcloud 30 which is no longer supported, so this is probably a "won't fix" but I think it's worth documenting it in case someone else has the same problem.

Research direction
Start by examining the reported apps/calendar/calendar and apps/calendar paths, then inspect apps/calendar/lib/Dashboard/CalendarWidget.php around line 106 and the automatic upgrade result. Reproduce the upgrade from an older installation if possible and verify that version 5.5.12 places the app files directly in apps/calendar without causing the reported missing-image crash.
