Seems like the version of pytest you installed is missing pytest.compat._translate_non_printable. What version of pytest do you have? Can you try updating the version and see if it repros?

[ttSpace]

@StellaHuang95 The Python installed from Microsoft Store.

[StellaHuang95]

I am now able to repro it. It's an issue within the pytest 8.1.0. This version has been yanked, see https://doc.pytest.org/en/latest/changelog.html#pytest-8-1-0-yanked.

Once I revert back to 8.0.2, I was able to run tests without any issues.

[EJelmer]

This is still broken in pytest v8.1.1.

This appears to be back with pytest 8.3.2 (python 3.11) in visual studio 17.11.1.

Did anyone have a permanent fix for this?
