Hey @Michael_Romagne, apologies for misunderstanding your issue earlier! I see now you’ve already tried the python.languageServer settings, my bad.
To answer your question: Pylance is not supported within Cursor. Ravi from the Cursor team mentioned this here. The recommended replacement is Cursor Pyright, which they built as an officially supported alternative.
The official Cursor Python docs outline the recommended setup
If you had custom Pylance settings, you can run Cursor Pyright: Import Pylance Settings from the command palette to migrate them.
