I'm not sure if this has anything to do with the change in comtypes between 1.2.0 and 1.4.6?
Maybe they changed the import of the generated file?

Steps to reproduce:

1. Run scons source
2. Run code .

Actual behavior:

The IDE could not find a definition related to comInterfaces.
In VS Code:
For example, F12 in source\UIAHandler\__init__.py could not find the definition of UIA.UIA_FrameworkIdPropertyId.
No autocomplete etc.

Expected behavior:

The IDE can find definitions related to comInterfaces.
