问题
When I run flask run on Windows, I get the following error
C:\\Python37\\python.exe: No module named C:\\Python37\\Scripts\\flask
This was working previously, the issue started after I created a new env recently.

This was a bug introduced in Werkzeug 0.15.5. Upgrade to at least Werkzeug 0.15.6, which contains the fix. You can also run with python -m flask run instead to work around it.
