Python Language Server Randomly Fails

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The python language server seem to stop randomly working for the last few days. type annotation, jumping to code references and related pytest fixture functionality doesn’t work

What are we seeing in the video?

Normal cursor usage, I have been working on python tests using pytest and fixtures for a while now and you could have always jumped to the definition reference by ctrl+click the fixture name on the test, demonstrated working

after window reload it stops working and shows in-file references mostly

after disabling the python extension, reloading (important) and enabling it again the ctrl+click and colors return to normal operationhttps://drive.google.com/file/d/1dJtprhRlZedI8n_mo21JgfHcKFJApEBS/view?usp=sharing

Steps to Reproduce

  1. Sometimes you just need to wait enough time
  2. just open the ide and it doesn’t work.
  3. reloading the window can cause it not to work too.

Expected Behavior

Not failing randomly.

Operating System

Linux
