[PyQt] Win32 Error with PyQt 5.14.1

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

   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?
