The navigation to go back one level can go missing when on album view. Will need more time for exact reproduce steps, but it happens more often than not.
Not having a keyboard shortcut to go back does not help with this bug.
Thanks. I responded in the discussion about the keyboard shortcut: https://discussions.apple.com/thread/251309275?answerId=252525023022#252525023022
Will report the problem with the disappearing button to Apple directly, when I find the time.

As noted in your other thread. the keyboard shortcut is different in German. Details in Tastaturkurzbefehle in der App „Musik“ auf dem Mac - Apple Support.
