Default Virtual instrument freezing?

Sorry if this has been addressed:

This is most frequently occurring when doing a bounce with Garritan player (CFX Lite), but I've also had it happen on Air Xpand.

After doing a bounce the VI will not play anymore. I have to deactivate the VI and then reactivate and then it's fine until after the next bounce.

Macos 12.3.1 and the latest version of Pro Tools, although it happened with the earlier versions.

I don't remember this happening on Big Sur
Running Pro Tools 2021.12
Main System 2020 M1 Macbook pro 13 inch / 16MB Ram / 1TB SSD / Big Sur

Future System 2021 14inch M1 Pro / 16MB Ram / 512 / Monterrey

Just tested with XPand on my system and the VI is still working after a bounce. Not sure if it's a Big Sur issue or not - I'm on Catalina.

I have found that as my (M1) CPU usage rises, MIDI playback is the first thing to suffer. Not that the system is overloaded but if I have a load of plugins running then MIDI tracks can stop playback. If I disable the plugin which are high in CPU usage, VI tracks start to play once again.

Maybe this is a similar issue to the one you are experiencing?
