Yup it seems stuck indeed, and Gadget is messy imho.
In my case here I simply removed this Module instance from AUM and my "Layers" channel, and replaced it with the AudioKit Nerd Synth. Since I am not (yet) doing any live shows, I am in the meantime building my possible rig options and getting familiar with these, just trying to make sure everything is solid before I sit there in a rehearsal room one day.. As I opted for Pianoteq for, I only have one Module instance left, for electric pianos, and so far this has not created any intermezzos for me during practice playing. Will att some point have a look at the Pianoteq electric pianos as well though.
What buffer size are you guys normally using? I have opted for 64 samples, as this works great in the Air M1 iPad, I started at 32 to see how that worked out but some instruments seemed to have a tendency to hickup on that even though the CPU usage was nothing to talk about.
