Power BI Python ADO.NET: Python Script Error

GREAT that you think you've "solved" this aggravating error (I have just encountered it for the first time TODAY)... 
... but it's INSANE to think UNINSTALL-then-REINSTALL is actually a "solution" 😮 !!!! @ POWERBI GODS - what's the REAL solution here ??? I can'te even get a simple numeric x,y plot work work, with only 4 lines of python code, so SOMETHING IS VERY WRONG HERE... 

PLEASE PLEASE HELP, and DON'T-FOR-THE-LOVE-OF-ALL-THAT-IS-HOLY tell me "uninstall then reinstall PowerBI". 
You MAY as well tell me "get a new LAPTOP" is a "solution" - !@#$%^&*...
