Python 3.8 memory leak

[danmash]

Type: Bug

I see high memory consumption; it happens after the Django runserver restarted.

[IllusionMH]

Looks like issue with one of Python related extensions or code executed by Python, not VS Code editor itself.

@IllusionMH As you can see in the issue description, I use Microsoft's Python plugins. How could I report this issue to them?

[danmash]

I suspect it's a MS black formatting plugin
https://marketplace.visualstudio.com/items?itemName=ms-python.black-formatter&ssr=false#overview

I see it could have happened after some invalid Python files.
