ERROR conda.cli.main_run:execute(47). Could not load py2 as interpreter

[PigeonXiong]

Type: Bug

Behaviour

Expected vs. Actual

The choice of python interpreter only pops py3 envs, no py2 envs.
When manually choose the py2 env executable, error occurs.

Steps to reproduce:

1. Use conda to create virtual env with py2.7
2. Load the executable as python interpreter

• Python version (& distribution if applicable, e.g. Anaconda): 2.7.18
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Conda
• Value of the python.languageServer setting: Default

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

We don't support python2 anymore. If you need to work with python 2.7 you will have to pin to 2022.2.* version of the extension, which was the last version that had the debugger (debugpy) with support for python 2.7, and was tested with 2.7.
