Hi! Manually installing the Pylance extension is unsupported. We did release our own Python extension; could you try that? You can find it by searching for @id:anysphere.cursorpyright in the extension search box (attaching a screenshot).
I installed it but it doesn’t do any difference.
Installing anysphere’s python automatically installs ms-python extension suite.
And the tests discovery is still messed up.
Without getting this year’s version of ms-python it probably won’t work.
I am keeping vscode installed now so I can run tests on it.
