Hi Mitchy,
I really apprecite your work. Thank you so much for putting in this time! I have been learning to use your add on and it has been previously working fine for me. However - I have just downloaded Blender 2.83 and Keep receiving the below issue. I have activated the auto Python script… Hope that you could guide me in the right direction! I’m attaching the screenshot of the error below 
Arigatou gozaimasu!!
