That's an old version of PyQt. With current versions you will get the 
same thing if you import Qt6. You are importing what Python thinks is a 
namespace when it is actually the root of the Qt6 installation.

The first step is the eliminate the use of the Qt module from your PyQt5 
code. Replace it with the modules that are actually being used.
