GH: unexpected Rhino crash.

Not sure if this is speckle related or not. I had 3 GH definitions opened and I was moving around between them. Then jumping from one definition to anther one, suddenly rhino just crush.

From the stack trace, it looks like something thrown by the graphql client lib that we are using. We’ll investigate!

OH! thanks for this, it will be super useful! I’ll try to reproduce your steps and hopefully we can find the culprit of this nasty crash!

If the receiver is still “receiving” while you do the change, we may just need to listen to the proper event and cancel any operations that are on going. GH does not like things happening in “non-active” documents.
