macOS 26.2 Music sync lost

[locksoft]

After upgrading Tahoe to 26.2 my Music plugin (it shows the current song in the menubar) sometimes looses the synchronization and doesn't change anymore with the new songs.
I can't say exactly when and how, because I'm not able to reproduce it, but after some songs I see the title is stuck to a previous one, and all the menu commands (like "go to Music" or "Play /Pause") don't react anymore. The only solution is quit Xbar and start it again. And it will work for a while.

Any idea?
