SOLVED: Library scan fails

[Mobilis]

Hello Everyone ! Newbie here...

[*]The version of Jellyfin you are running (e.g. 10.8.10)
[*] - 10.9.1

[*]Your installation method and platform (e.g. Linux Docker, Debian repository, Windows installer, etc.)
[*] - docker on a Synology NAS

[*]A brief description of the issue as your thread subject, using the description for additional important context only if required
[*] - Library scan fails when I add specific files to a music library

[*]A full explanation of what is happening, versus what you expect to happen
[*] - Everything was working quite well then I decided to add my music to a library, and from then on scanning started to fail systematically. So I removed the files and scanning worked again. Then I tried to re-add music, artist by artist (painfully). Some work, others break the scan. I can't figure what is wrong. My library consists of mainly Ogg files with occasional Flac. No other files at all (no jpg, no nfo, nothing). Files have been tagged and renamed via Musicbrainz Picard. I have spent hours on this trying to figure why, some files work and not others...

[*]What client(s) you are using and how the issue manifests
[*] - not a client issue obviously but I'm using the WEB UI in firefox

[*]Any other context you might think is relevant
the error log shows this

Solution possible here: https://github.com/jellyfin/jellyfin/issues/11528  which would be to change DOTNET_SYSTEM_GLOBALIZATION_INVARIANT set to true or 1 in the env file.

Maybe that will fix it.

Man: you saved my day !
Removing the said variable completely fixed it for me !!!
Thanks a lot !
