The two files being reported as corrupt (utc.app.json and telemetry.ASM-WindowsDefault.json) are false positives. Microsoft is aware of the issue and said that they'll fix this in a future update. For now, these files won't affect your system at all.
Can you try to reinstall the Windows Updates? If they fail, upload the two files below for me please.
C:\Windows\WindowsUpdate.log
C:\Windows\Logs\CBS\CBS.log
Also, let me know what error code it fails with if it does.
