Standalone install also failed for me. There is something very wrong with this update.
Yeah and I don't know about anyone else, but mine consistently fails with an Error code: (0x80070003). I have never had any Windows Updates issues with this current system. Looking around I'm seeing quite a lot of reports regarding this Windows Update specifically. Seems like the kind of issue to review the update about. KB5055523
Same for me, both installation methods fail. I'm also getting 0x8000ffff and 0x80248007. SFC /scannow says there is a system repair pending requiring a reboot but nothing happens on reboot. DISM scanhealth and restorehealth fail with 0x8000ffff.
