It's totally expected to get errors with corrupted files, but there should be some indication, error or task completion, even if there is a problem with one specific file.
In my opinion, this could be improved on.

If you open the logs for Jellyfin, you can actually see what's happening in real time.

If you open them through Jellyfin's dashboard, just reload (F5) the page constantly to see the real-time updates.
On Truenas Scale's GUI, the log view window should be updating in real-time for a bit.

On the first set of logs you posted, I do remember seeing a mention of some path to an anime library. You edited out most of the path to a bunch of 'X' characters, but that could be the folder/file that's giving you issues.
