DISM and Windows Update issues after upgrading to Windows 11 25H2 via Flyoobe

I upgraded my system to Windows 11 25H2 (build 26200.6584) using the Flyoobe tool.

Since the upgrade, all DISM commands fail with error 0x80070057 (“The repair content could not be found”). The log shows DISM version 10.0.26100.5074, while my system build is 10.0.26200.6584, it seems the Servicing Stack wasn’t fully updated.

Also, the cumulative update KB5065789 fails to install with error 0x80070306.

Questions:

1. Is this partial Servicing Stack version intentional in Flyoobe (for compatibility reasons)?
2. Is there a supported way to sync or update the Servicing Stack / DISM to match build 26200?

Thanks in advance for clarifying and helping investigate this.
