“In order to use Anysphere Python, ms-python.vscode-pylance must be uninstalled” renders Cursor unusable

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Upon startup, an error notification appears: “In order to use Anysphere Python, ms-python.vscode-pylance must be uninstalled.”

Code intelligence (following symbols, etc) fails, and I no longer trust the LLM features since a core part of the language server(s) seem inoperative.

Suggested solutions do not fix the problem. In another thread, it was said that something was fixed behind the scenes, but this is either false or insufficient for me and other users like me who’ve gone ignored in that thread even though we’re paying corporate customers.

This renders Cursor useless, which is obviously an unacceptable “blocker” scenario.

Steps to Reproduce

Start up Cursor with standard extensions (including Python from Microsoft). Open a Python file in a project

Expected Behavior

Language intelligence and context for LLMs.

Operating System

MacOS
