Jellyfin suddenly shuts down on start

[Efficient_Good_5784]

Full: SQLitePCL.pretty.SQLiteException: database or disk is full

From your log, this would indicate that you have some disk issue where your Jellyfin database is located.

Is the drive where you have your Jellyfin config folder located full or near its max capacity? If not, maybe it's a permissions issue if you were messing around with those around the config folder.

Another thought, do you have your transcode folder set to the same location as the config folder? As clients fill up the transcode folder with transcoded videos, this could be making the drive reach max capacity leaving the database with not enough free space to operate.
Same thing could apply for the cache folder if it's getting big enough.
