Python Debugger won't launch for conda envs

[araguilar1]

Issue Type: Bug

Behaviour

Debug overlay appears for a brief second, and then nothing happens afterwards.
Ran suggested command in #18436 (comment)

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

Exactly the same issue. The pre-Release version v2022.5.10911002 does not work, either. Only the older version works.

[daholste]

Same here. Older version works for me as well. Only happens when I start VS Code by typing "code" from activated environment on Miniconda, which I need to do

Workaround --> Temporarily downgrading to v2022.2.1924087327
