Python interactive window not working

[PrateekArya]

Issue Type: Bug

Python interactive stopped working just after updating to the current insider build.
Disabled all other extensions except for python, updated python extension, reset all python extension settings to default, restarted my computer, etc. Nothing seems to be working. Its stuck at "Executing Cell" status and the "Python Interactive" window frame is completely blank.

Steps to reproduce:

1. Open any .py file with "#%%" for marking cells.
2. Execute any cell.
