Actual behavior

Opened a folder with a single empty hello.py file:

No python interpreter is selected, and I get this error message immediately after opening the file

Expected behavior

The dialog should instead say something like

No Python interpreter is selected, you need to select a Python interpreter to enable features such as IntelliSense, linting, and debugging.
