Some program errors (including Python errors) can cause an error popup window to appear. This error window stops automated scripts from further progress. This is a big problem for long-running Python scripts that call other programs, perhaps on a Task Schedule.
However, the downside to disabling the error popups is you may not know a problem has happened without looking at program logs (if they exist).
Disable Windows Error popups:
Press WindowsKey + R (Run) and type
Go to Computer Configuration → Administrative Templates → Windows Components → Windows Error Reporting and configure as desired.
