I'll be damned, I searched twice before creating this issue.... once done I finally found #1404 witch is the exact same thing but this time for 1.10.3

A forced reset of the container ix the boot trooble

Recreate the container from scratch. What you describe looks like some issues when updating with Watchtower.

Same Problem here after update from 1.10.1. @SylvainDx : Can you please advise me, how to do a "force reset"? Will I loose my current komga database content? I run a Synology DS918+ with DSM 7.2.1-u4. Thank you.

Edit: is it sufficient to backup (copy) the database.sqlite file; reset container and then restore the database file?
