Can't import default pyqt6 wheels on windows

[Patrick Stinson]

I get a DLL linking error with a clean python 3.9.13 install and "pip install pyqt6" on windows. This occurs on every machine I try it on in our lab, whether windows 10 or windows 11. Installing "pyqt6-tools" gets me going for just pyqt6. I am doing a lot of pretty basic stuff so I am not tied to a particular pyqt6 or Qt6 version.

Now I want to use pyqt6-charts and I am getting the DLL error again: "DLL load failed while importing QtCharts: the specified procedure can't be found."

Are the pyqt6 wheels all really broken? Is it my python version? The wheels do include the qt binaries so what is going on? This problem is easily reproducible so I thought there might be a straightforward answer here.
