Cubase 12 Mixer with Console 1 Fader- jitter / sometimes unresponsive

I’ve had great success using Console 1 Fader with Cubase. Infrequently (2 incidents) a single channel fails, in the Mix Console the volume values are cycling through a small range. Cubase mix console and physical console 1 fader are unresponsive, have to delete the Console 1 insert.
Anyone experience similar issues?
