it looks like there is a bug around untitled.ipynb with LSP experimentation on.

repro steps are

1. set "python.pylanceLspNotebooksEnabled": true
2. make sure no folder is opened.
3. from menu, file -> new file ->jupyter notebook

Just to add to this: as a quick fix, given that you do not need the LSP experimental mode, is to turn it off.

FWIW I have just been able to reproduce this by creating a new untitled notebook with a folder open in VS Code.

Having the same issue. Setting python.pylanceLspNotebooksEnabled to false did resolve the issue for now, but then I start getting duplicate suggestions from IntelliSense in .py files after having opened and run a Jupyter notebook. Setting additionally jupyter.pylanceHandlesNotebooks to false gets rid of those duplicates as well and makes things usable for me again.

This resolves the issue I had for now. Pylance loads properly for me with python.pylanceLspNotebooksEnabled set to true, as long as I do not have an unsaved Untitled.ipynb open.

This issue has been fixed in version 2022.8.12, which we've just released. You can find the changelog here: CHANGELOG.md
