Vital clicking with Ableton Live 11 Suite

Hi - I’ve tried all of the obvious things - Set Ableton Audio Buffer to a max of 2048, set Vital Oversampling to 1x, and when I play the Vital Keystation preset, it pegs the CPU - I am running on an M.2 SSD on a 2015 MacOS 11 laptop. It also clicks with many other presets.

I have not seen this issue with any of the Native Instruments Komplete 13 instruments that I also own.

Is there anything else in Vital that I could disable?
