Windows 10: Bluetooth broken with Python 3.12

[chrisgeli]

While investigating hbldh/bleak#1529, I came across this behaviour:

Python 3.12.2 (tags/v3.12.2:6abddd9, Feb  6 2024, 21:26:36) [MSC v.1937 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import winrt
>>> import winrt.windows
>>> import winrt.windows.devices
>>> import winrt.windows.devices.bluetooth
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python3.12\Lib\site-packages\winrt\windows\devices\bluetooth\__init__.py", line 6, in <module>
from winrt import _winrt_windows_devices_bluetooth
ImportError: DLL load failed while importing _winrt_windows_devices_bluetooth: The specified module could not be found.

Knowing very little about WinRT, I'm not sure this is expected.

Version info:
Python version: 3.12.2
