Specific pip package (and its associated modules) "upbge-stubs" #1825

So, theres this package https://pypi.org/project/upbge-stubs/ which comes with a set of modules created entirely for syntax highlighting when developing with the game engine "Uchronia Project Blender Game Engine".

Supposedly the package should allow for syntax highlighting with PyCharm in a Linux environment without issues (according to the creator of the package). I cant get it working with a fresh install of VS Code & Python on Windows 10.

Cant quite figure out what the issue is, but funny enough, even VS Codes Python Extension appears to recognize the submodules when typing "import bge.", but not when you actually attempt using any of the modules.

To demonstrate this:

Now, Im not certain exactly why this particular package isnt being interpreted properly by the python extension, but any knowledge on the topic would be appreciated, its unclear if there are any potential bugs related to VS Codes python extension that prevents the module from loading properly.

• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): pipenv or no environment (doesnt appear to affect the issue)
• Relevant/affected Python packages and their versions: https://pypi.org/project/upbge-stubs/

Expected behaviour

I expect code completion to be fully functional

Actual behaviour

I have no code completion and operations such as "Go to reference" results in "no definition for ..."

Steps to reproduce:

Install a fresh install version of VS Code in a self contained environment (or well, that would be the ideal scenario as I have no clue at all why I dont quite get autocomplete for this module working.

Install Python v 3.9.6 from Python.org, double check that your path is correct and configure VS Code to utelize this newly installed interpreter (view > cmd palette > select py intepreter > 3.9.6).

Run pip install upbge-stubs.

Create a new python file and add:

import bge

notice how if you start typing something like bge. you will get no syntax code completion - but, ironically, if you type import bge. you will get code completion - only when importing, but not when attempting to access the bge module as a separate expression.
