Problem with discovery in github actions & cibuildwheel

[dsimidzija]

As the title says, I've ran into a bit of problem with my github actions, because the cibuildwheel pipeline fails during the virtualenv setup, apparently during the discovery phase. This only happens for osx and windows builds.

This is an example log:

I'm not sure how to fix this, and I couldn't find it being mentioned anywhere in recent virtualenv or cibuildwheel issues. 😨 If someone can point me in the right direction, I'm willing to help find the cause as much as I can.

Seems /Library/Frameworks/Python.framework/Versions/3.10/bin/python3 prints some text that's not able to be parsed as a JSON. To find out why can you execute with that python this file https://github.com/pypa/virtualenv/blob/main/src/virtualenv/discovery/py_info.py#L1
