    Looks like you might have a bad update. Do the following to remove stale versions of the extension:

    1. Uninstall Python extension (if you have pylance uninstall it first).
    2. Close all instances of VS Code.
    3. Go to, %USERPROFILE%/.vscode/extensions (on windows) or ~/.vscode/extensions on Linux/Mac.
    4. Delete any folder with the name starting with ms-python.python*
    5. Start VS Code, and install Python extension (also pylance if you uninstalled it in step 1).

    Reinstallation of all extensions fixed it

    Same here. Thanks.

    edit: I realized that wasn't quite explicit. Reinstallation of extensions fixed it for me.

    Uninstall and reinstall (following the steps above) didn't work for me.

    ms-python.python v2021.5.842923320 is still crashing and printing the error above. I'm working with the Remote - SSH package.

    Any progress Austin Park (@austinpark77) ? I've been having the same problem for about 2 weeks and completely deleting the remote .vscode folder then reconnecting and reinstalling the python extension hasn't fixed it at all.

    I was OOO for the last week, so I didn't try anything. Today I updated to the most recent version of VS Code (v1.57) and Python Extension (v2021.6.944021595), ssh'd in, and it was working as expected. This probably isn't too helpful, but fingers crossed the update fixes your issues too.

    None of the solutions are working. Tried uninstalling the extensions and deleting appropriate folder from .vscode. But the language server keeps crashing.

    Is there any other solution out there other than waiting for next update and hope that fixes the issue.

    File -> Preferences -> Settings -> Extensions -> Python -> "Python: Language Server".
    or search for it in settings "Python: Language Server" .
    change it to Pylance

    I was working on a remote machine using Remote - SSH.
    Setting the language server to pylance fixed it for me.

    Changing the language server to Pylance fixed things, but dear god do I hate the color scheme. Why do we need to have this as Pylance?

    That doesn't work for me. When I check the language server output, I got a stack overflow error when I try to use numpy functions. If a source code file contains import numpy as np, the language server fails.

    Adding the line "python.languageServer": "Pylance" to the file .vscode/settings.json solved the issue for me.
