Windows 11: Reinstall breaks Microsoft account sign‑in (OneDrive, Store, Feedback etc.)

I have a serious authentication problem on a newly installed Windows system that makes the laptop almost unusable.

This is a clean, recent Windows installation (not an upgrade). There is effectively no update history to roll back to.

I can only sign in to Windows using a local account. Any Microsoft account–based sign‑in (for example adding an account under Settings, OneDrive, Store, Feedback, support) either fails or hangs.

OneDrive cannot sign in at all, so syncing files is impossible.

Microsoft Store fails with an authentication / connection error and will not let me download or update apps.

Feedback Hub and other built‑in apps that require a Microsoft account also fail to authenticate, which means I cannot use the standard feedback and support channels from this device.

I have already tried multiple full resets / clean reinstalls of Windows on this laptop. The symptoms return immediately even on a fresh installation.

Because all Microsoft account authentication on this device is broken, your normal guidance (use Feedback Hub, sign in to Store, or roll back specific updates) is not usable in my situation. This is not an enterprise machine and not using a cloned corporate image; it is a personal laptop that should work out of the box. There is no problem with my personal account, and this is genuine Windows.
