How to fix error when installing PyQt5?

Question

How to overcome the qt.qpa.plugin error when running a script with PyQt5?
Installed pyqt with pip install pyqt5.
Today I did everything as usual, and when I run scripts containing PyQt, I get the following.
qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Reinstall doesn't help
