Logic Pro MIDI playback distorted with 3rd party plugins

Hello,

My Logic Pro Midi playback when using 3rd party plugins has recently started making a harsh distorted sound. This only happens when I use 3rd party plugins and not the stock instruments. The distorted sound persists regardless of what my audio output is. I've tried to do a 'Full Audio Unit Reset' but this did not solve the problem.

Any ideas? Thank you, thank you

I am on a macbook pro (2021) Sonoma 14.3.1 and am on Logic Pro version 11.0.1
