Music app library songs are not playing after macOS update to Tahoe 26.4

After updating to Tahoe 26.4 my songs from the library were simply not played. Apple Music and Radio were working. I tried deleting Cache and plist, without success.

In the Music app I then went under Settings > Files and just clicked "Change" and confirmed the path without changing anything. After that it worked! (But maybe previous deletion of cache etc. had an influence too. I couldn't verify that)

Hope that also helps other people as a first step to tackle this issue.
