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

Follow‑up:

Thanks for reviewing my initial report.

I want to add a few technical details that may help determine whether this is a known servicing issue in the 26220.x flighting line.

- The device is on Windows 11 Home Insider Preview 25H2 (OS Build 26220.8925).

- The pending update is Windows 11 Insider Preview Feature Update 26220.9022, but it never progresses past 0%.

- The earlier update failure on 8/1/26 due to low disk space appears to have left the servicing stack in a faulted state. Disk space has since been fully restored.

- Windows Update Troubleshooter fails to launch, which suggests CBS or servicing stack corruption rather than a simple download issue.

- No other updates (drivers, cumulative, or definition updates) will initialize.

- The build is approaching its evaluation expiration (8/11/2026), so the system is attempting to migrate but cannot stage the payload.

Given these symptoms, this looks like a build‑to‑build migration failure specific to the 25H2 Insider servicing baseline.

I’d appreciate confirmation on whether 26220.8925 → 26220.9022 has any known servicing stack issues, or if a manual servicing reset / repair package is required.

Thanks for any guidance the Insider engineering team can provide.
