SOLVED: Can't "parse/scrape" all music into library

[alike]

I tried deactivating the playback reporting plugin, restarted and tried "look for missing metadata" and "look for changes" on the troubled library. Still the same however, the same error message in the log. I also deleted a plugin called "reports" that wasn't so useful anyway, and tried again: same result.

Here's more logdata:

BTW any idea what creates this message? Its new for me:

Code:

[2025-04-05 10:40:39.976 +02:00] [INF] [29] Jellyfin.Api.Auth.CustomAuthenticationHandler: AuthenticationScheme: "CustomAuthentication" was challenged.

I have a small windows app called "restart on crash v1.6.4.0" that restarts crashed services and apps that always should be running, and when the server app is closed it automatically tries to restart it using the script. I see then it is not able to come past that message. Something with permission if I had to guess?
But even when I just run the app the "normal way" this message is present quite often in the log.

I have another plugin that have its icon deleted, so I am guessing its something with permission on the plugin file? Any thoughts on that?
