Muse Sounds instruments sometimes cut out when making changes in the mixer

Using MuseScore 4

In my file I have a mixture of MS Basic instruments and Muse Sounds instruments.
If I change the instrument sound assignment or mute and unmute tracks, one in every 3 or so times, all Muse Sounds instruments will cut out and I have to restart playback to fix this.

In addition, when changing the sound of metronome to a Muse Sounds instrument, the metronome became out of sync with the music.
