Hi TheDreadPirate,

first of all thank you for your answer/question and during my research I saw that you are an extremly helpful member of this forum.

Due to your question, XML files did exist and with this in mind, I had the Idea to just restore an one month old backup to solve the problem. Now I might made things worse. -.-

The backup seemed to actually work, because all shared paths were added, but now I get this error message and don't know why it comes up or how to fix it...

Do you have expirience with this error or can tell me how to I probably could fix it. Might there be a problem with the database because I was running Jellyfin 10.8.13 when I created the backup? Or could it be that there is a problem with overwriting still existing database when restoring? Jellyfin docker was stopped while running the backup. ´

I really need help here. Building up all data from scratch won't be a real option.

PS: This is the second time when updating Jellyfin, that I had big problems afterwards. In the future I should stick with: "Never change a running system!"
