That should be the issue one would think, but it is disabled in Devices. As for the plug-in window, I don’t know if disabling each and every plugin-in would help however I did change my system to prioritize Background Services and that seems to have fixed it in a manner of speaking but occasionally the metronome gets muddled at the start.
Whatever the problem, this is something I think needs to be addressed in a compatibility update.
