SOLVED: Jellyfin destroys itself.

[RostigerSpieler]

I am currently having problems with Jellyfin again. When the server self-destructed, I was using version 10.9.7.

The problem occurred when I was watching a movie. While watching a movie, the movie stopped in the middle and the server crashed.

Then I checked my PC where the server was running. The hard disk there was full. So I cleared the hard disk and now have over 40GB available again.

However, I can no longer start the server. When I try to start it, it always crashes immediately with the following message:

So I installed version 10.9.8 in the hope that this would solve the problem. Unfortunately without success.

What can I do now? Which files do I have to back up to do a complete (new) reinstallation?


Server: Windows 11 (AMD Server)
Server Version: 10.9.7 / 10.9.8
