Cancel the Setup and re-run it. In the initial screen, click “Change how Setup downloads updates”, and click "Not right now".
That might help.

2023-10-01T11:40:03+00:00 No need to Reset the PC. You can repair Windows 11 using the Media Creation Tool or ISO. That should take care of the CBS errors like 0x800f081f.
