Actual Behaviour

Expected Behavior (this is without PyLance)

Description

Hi, my colors in the my text editor are totally messed up when turning on PyLance. I never observed this before and I can't remember what I've changed. I see this behavior mostly in Jupyter Notebooks, but it make reading my files almost impossible :(

Does anyone have an idea what could have gone wrong? I'm happy to provide more context, but I have no idea what information I could provide you to resolve this issue.

I have encountered the same problem today. I was going crazy as I thought I messed my extensions up, but after a few hours of playing around and googling I found out that Pylance is indeed somehow broken in Jupyter Notebooks at the moment. It works well in the native Python environment, but in Notebooks the highlighting is ridiculous and annoying.
In addition to that IntelliCode also does not work with Notebooks, again probably because of the Pylance issue.

VSCode version: 1.61.1
Pylance: v2021.10.1
Python: 3.9.6 64-bit

This is #1932; there are ongoing issues with notebooks in the browser as they are not handled the same way as Python notebooks are in the desktop.
