Sometimes I get the 500 error when trying to view the PCB in 2d or 3d. and I have to clear all of my cookies and site data to get it to work. I found that recently if i just "spam" click refresh in the browser it will display - this has heppened to me on several windows laptops. I also think it is tied to co-pilot. like, if copilot wanted to do something and you didn't let it, it would get pissy with you and give you the 500 error. Another fix i have found to work on occassion is to delete the copilot chats.

COpilot times-out after 9 minutes and it throws non-stop errors till i delete that chat.

Copilot doesn't seem to have the memory to do multiple tasks, like it forgets what its doing after the first operation.
