SOLVED: Jellyfin crashes when scanning Library

[TheColin21]

My Jellyfin recently started crashing when I try to scan my movies library.
I recently removed .ignore files from my extras folders as I wanted to integrate them with Jellyfin.

Before the crash the following gets logged:

Code:

I included just 3 lines of ffprobe starting, there are quite a few more.
New files do get found, there was a missing movie before I scanned for example, but no metadata is found. Metadata only gets searched when I manually select update metadata for a single movie.
The extra files do not appear in Jellyfin.

File permissions are correct, I triple-checked that.

Any ideas what might be causing this?

Can you share your full jellyfin log via pastebin?

I had to cut it quite a bit short but here it is:
https://pastebin.com/t5h5Mtsa

I pseudonymized my domain and a few IP addresses.

It keeps failing on Ant-man and/or Independence Day. Specifically Ant-man "t10" and Independence Day "t06". Remove both of them from your library/extras folder then scan and see what happens.

Thanks, I was able to get it working.
I suppose you just singled them out because they were the last files listed before the crash?
I continued like this and singled out six files overall that were causing problems. Each an extra from a different BluRay
Some others still threw errors, for example:

Code:

I saw this one quite a lot for different files although I don't know why Jellyfin queries any metadata provider at all for extras.

This does not really bother me though as it at least doesn't crash the whole Jellyfin server.
I think there should be some kind of better error handling than restarting the whole server when a scan finds a file that it cannot handle for some reason - especially without obviously alerting the user.
