Cumulative update install failed (Release Preview)

You can try unenrolling from the Release Preview channel and then re-enrolling. This can sometimes reset things. However, only do this as a last resort because it might mean you have to reinstall Windows.

I have been having the same issue after Windows 11 24H2 was installed on 11/26/2024. In fact, my onboard camera can no longer be found, and the Bluetooth function disappeared from the bottom right systems window.

As for my system,
