Python Debugger won't launch for conda envs

Issue Type: Bug

Behaviour

Debug overlay appears for a brief second, and then nothing happens afterwards. Ran suggested command in https://github.com/microsoft/vscode-python/issues/18436#issuecomment-1030280077

Got this output: Content-Length: 137

{“seq”: 1, “type”: “event”, “event”: “output”, “body”: {“category”: “telemetry”, “output”: “ptvsd”, “data”: {“packageVersion”: “1.6.0”}}}Content-Length: 139

{“seq”: 2, “type”: “event”, “event”: “output”, “body”: {“category”: “telemetry”, “output”: “debugpy”, “data”: {“packageVersion”: “1.6.0”}}}

Expected vs. Actual

Expected: launch python debugging session Actual: debugging session does not launch, no indication of error.

Steps to reproduce:

1. Install python extension v2022.4.0
2. Install anaconda python, conda version 4.12.0
3. Create python 3.9.7 conda env
4. Launch python debugger with F5 or via menu on any python script
