Make sure that core isolation is tuned on in Windows Security and try again.
That doesn't seem to make any difference, I updated 2 different machines one with core isolation on and one off, they both worked fine for me.
The 0x800f0911 0x80070002 errors are caused by something else.
Other users on this thread have worked around the problem doing the update using an ISO file instead of W.U.
Perhaps that is the solution while waiting for a fix from MS. π
Even this device below, which does not meet the Windows 11 Requirements updated to 22621.232 without problems. π€£π
