Python test discovery blocks extension host

[shicaiv]

Type: Bug

Behaviour

After opening test explorer, discovery of python tests starts and blocks all other extensions

Steps to reproduce:

1. Just open text explorer and all other extensions will block

Diagnostic data

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

Downgrading python extension to 2024.20.0 solves the issue.
