OS Build 26220.8925 Win 11 Home Insider Preview Feature Update stuck at 0%

A few details that may be relevant:

- The device previously failed to update on 8/1/26 due to low disk space.

- Disk space has since been fully recovered and verified.

- After resolving storage, Windows Update resumed but never progresses past 0%.

- Build‑to‑build migration appears to be failing (25H2 → newer 25H2 servicing build).

- The Windows Update troubleshooter fails to launch, which suggests a servicing stack or update component issue.

I’m looking for guidance from the Insider team or anyone familiar with servicing failures on this build line. Any known issues with 26220.x migration or recommended recovery steps

(resetting update components, servicing stack repair, etc.) would be appreciated.
