[PyQt] Win32 Error with PyQt 5.14.1

[Doug Bell]

Hi,

I've run PyQt on an older PC with Windows 10 for a long time.  But after
installing PyQt 5.14.1 on a Python 3.8 32-bit install (using "pip
install PyQt5"), I get the following error when trying to run any PyQt
application:

   ImportError: DLL load failed while importing QtCore: %1 is not a
   valid Win32 application.

Installing PyQt 5.14.0 gives the same result, but it works fine after
installing PyQt 5.13.2, with no other changes.

Any ideas?  Did something change in PyQt 5.14?

Thanks,
Doug
