Language server fails to start #19737
Description
Type: Bug
Behaviour
Expected vs. Actual
Language server is expected to start, but doesn't. This issue only happens on the pre-release version. Works fine when I switch over to the stable release.
Steps to reproduce:
- Load a python project in vscode
Diagnostic data
- Python version (& distribution if applicable, e.g. Anaconda): 3.9.12
- Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Poetry
- Value of the
python.languageServersetting: Pylance
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
Python interpreter path: ./.venv/bin/python
