Microsoft has confirmed that Windows 11 Shell and every associated core feature and element are actually broken, and have been like this for many months.
Last month they broke audio drivers, so USB connected speakers were not being recognised unless they had third-party drivers. The native windows drivers just stopped recognising them as audio devices, and just listed them as Unknown Device.
Windows could see them, it had no idea what they were, or what to do with them. So you had no audio.
The only solution was to continuously restart until eventually it randomly worked.
