Please, try:

Download file PyQt5-5.15.4-cp36.cp37.cp38.cp39-none-win_amd64.whl from the page https://pypi.org/project/PyQt5/#files
Rename it to PyQt5-5.15.4-py3-none-win_amd64.whl
Run pip install PyQt5-5.15.4-py3-none-win_amd64.whl

I was able to install it into Python 3.10 virtual environment, then was able to run example from https://zetcode.com/gui/pyqt5/firstprograms/

Thank you Andrew. I banged my head on this topic for a long while before stumbling upon your answer. I didn't realize the file needed to be renamed. "I didn't get the memo."

Additionally, 5.15.5 will be released soon, but you can download it from riverbankcomputing.com/pypi
