I updated recently CP to 3.0. I have a message error that I never encountered before.
It looks it happens during the ExportToSpreadsheet:
I saw a similar topic Assertion error on start-up. Apparently, closing the eye solved the problem in this case. However, in my case, closing them does not solve it.
This is pretty annoying as it stops the overall processing from going any further. A quick fix would be to disable any error message from popping up. Is it possible?
