Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Steps to reproduce:

1. start vscode without any open file
2. open any .py file, with or without #%% markers
3. wait for Python task to show up in Task manager grouped under Visual Studio Code
   
4. Close VScode and wait for a few seconds
5. A rogue Python task remains running with high CPU and Power usage
   

Expected behaviour:

All python processes should close when exiting VScode

Attempted debugging

Disabling the jupyter extension in VSCode solves the problem.

Changing python language server settings as in the issue (with similar symptoms) in #15586. i.e. adding "python.experiments.optOutFrom": ["pythonJediLSP"] and "python.languageServer": "Pylance" to settings.json. This did not solve the problem.

According to the task manager, the command line for the rogue processes is: C:\Anaconda3\python.exe "C:\Anaconda3\Scripts\conda-script.py" "run" "-n" "base" "--no-capture-output" "python" "c:\Users\***\.vscode\extensions\ms-python.python-2022.8.0\pythonFiles\get_output_via_markers.py" "c:/Users/***/.vscode/extensions/ms-pyt
