Same exact issue as the one linked above. Bug appears after attempting to install plug-in in Blender. #

Install zip file to preferences.

Additional information

Restarting blender does not do anything on my end. Same error appears no matter the amount of times I restart the program, my computer, or add/remove the add-on.

Thank you for posting this again. I'm sorry it's happening for you! I just looked at this log and the one from #41. It looks like both are from Blender 2.8x. That's not actually a supported version for AI Render. It only officially works in 3.0+.

I would try to make it work for 2.83, since I know that's still a LTS version, but in my testing earlier, I had all sorts of python errors that I couldn't debug.

Actually, I will leave this open. Maybe someone who knows older versions of Blender can fix it!
