System.OverflowException:Arithmetic operation resulted in an overflow

Hello everyone!
I am using VisualComponents Premium 4.1 to edit the component python. The edited script cannot be downloaded, nor can I close the python editor window, and the error in the screenshot pops up. Can anyone tell me what the problem is and how do I deal with it?
I have tried restarting the computer, uninstalling and reinstalling the software, and none of the problems have been resolved.
thank!
