As of writing this, i have no way of knowing which xml file jellyfin is attempting to load, nor which ones passed / failed.
If someone has a script, or something (not super knowledgeable about xml stuff, or how jellyfin works, my area of expertise is in 3DCAD and Networking (vlans, switches, routing, etc)...) it would be incredibly helpful.

I also can't seem to find any documentation on adding debug flags to the .exe via CLI either, so any knowledge on that would be much appreciated. -- edit, even with the debug log options from https://jellyfin.org/docs/general/administration/troubleshooting/#debug-logging, nothing in the log output changes..... fan-flippin-tastic, was hoping the log would tell me which file it was trying to load... :C

It's failing on either migrations.xml or system.xml in the Jellyfin config dir, I think that would be %APPDATA%/jellyfin/config on Windows, but don't quote me on that.

[grillgamesh]

ah.... yep, it's definitely migrations.xml.

system.xml is all fine:

and BTW, it was C:\Users\%username%\Documents\Jellyfin\Server\config (or at least, thats what it is on my install, might be different from default, i don't recall if I specified a different dir than default)

[grillgamesh]

okay, so, I upgraded to 10.9.7 (noticed that the latest release was a bit ahead of me), and after upgrading to latest, I removed migrations.xml from the folder, attempted to start jellyfin and the file was auto-regenerated (no longer showing NUL across the board)... and now it's throwing a different error.. yay.... :\

Now, if only I knew where this table was being "read" from, and if it was okay to purge it like I did migrations.xml... 🤔

[Bond-009]

It's trying to do old migrations, try setting IsStartupWizardCompleted to false in system.xml, start the server so it generates migrations.xml, shut it down and set it back to false.

[grillgamesh]

absolutely incredible, it works!

[Furbach]

same problem, fixed in the same way. thanks

[grillgamesh]

I couldn't find this issue on the issue list already, so I did a write up for future searchers who have this issue.
Glad to see it's already helped someone else! \o/

[vallovic]

Same problem happened to me just today, glad I found this issue!

The only difference is that I'm using Linux (Native), so the configurations directory is /etc/jellyfin.
