Run button not working in python extension

[snate28]

Type: Bug

Run button doesn't do anything when I press it, however if I type "python filename.py" in the terminal, it runs normally. I've tried reinstalling vs studio completely and it didn't resolve the issue. I'm trying to configure vs code with my anaconda environment.

It looks like this is caused by the Python extension. Please file the issue to the Python extension repository. Make sure to check their issue reporting template and provide them relevant information such as the extension version you're using. See also our issue reporting guidelines for more information.

Happy Coding!

@snate28 It seems like pylance is falling to start. Try the following:

1. uninstall pylance from the Extensions view.
2. Close all instances of VS Code
3. Go to C:\Users\<your user>\.vscode\extensions directory and find pylance and delete it.
4. Start VS Code again and see if it works now (without Pylance)

@karthiknadig It still doesn't work without Pylance.

@snate28 I need to Output > Python logs this time.
