Type: Bug

Behaviour

If the default interpreter is set to a non existent (or deleted venv), Pylance will fail to launch.

Steps to reproduce:

  1. Create a folder
  2. Create a venv in that folder
  3. Create a python file in that folder
  4. Set the interpreter for that folder to that venv
  5. Close folder
  6. Delete venv
  7. Reopen folder
  8. No intellisense

Diagnostic data

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
