I've tried using Copilot to fix the issue. I've tried all the below and no success so far.

  1. Reload Visual Studio Code
  2. Check Pylance is installed and up to date.
  3. Check VS Code is up to date.
  4. Restart VS Code.
  5. Re-installed VS Code.
  6. {} settings.json only contains the below { "python.REPL.enableREPLSmartSend": false }
  7. Run VS Code as an admin
  8. Deleted the pylance files in C:\Users\user_name.vscode\extensions .. and then re-installed Pylance

@adrianrymill, how are you running VS Code? Is the server remote? In a container?
