Pause the updates and search again.
This fixed this issue for me. Just pause, and unpause - nothing else. No troubleshooting, no clicking links from unknown websites...
Seems that this update was removed by MS, and by pausing and unpausing WinUpdate cache is cleared, so it no longer appears there.
I ran the troubleshooter file wushowhide.diagcab as mentioned earlier, then paused and restarted updates as suggested and it worked for me on Windows 11. Thanks
