Jellyfin Server won't start

[inoffensivelama]

Hello,

first of all, I am new here. So if this is in the wrong spot please let me know.

Now to my actual issue. I installed jellyfin server on my hp elitedesk with win 10. (Version 10.8.13 with the installer)
I used the server for around 3 to 4 weeks with no issues. But all the sudden the server wasnt working properly anymore. So I reinstalled it. It worked again for 1 or 2 weeks. But now I just can't get it to run any more. When I doubleclick the app the small icon will appear in the bottom right (where the usb and other running services are shown), but as soon as I hover my mouse over it, the icon disappears. I tried reinstalling and turning on and off the PC many times but nothing gets it to work again.

Since this is a very weird issue (icon appears but then vanishes) I havent been able to find a solution for my problem.

I was only using the server locally.

My firewall is shut off completely and there is no jellyfin service running in the task manager.

I am looking forward to hearing any recommendations. I really like Jellyfin and would like to keep using it.
