Windows 10: Windows 11 updates are failing - error 0x800705b4

My Windows Update Center has been unable to download or install updates for a month. The error code is always 0x800705b4. When I click "Check for updates" it refreshes endlessly until I shut down my PC for the night. Windows Troubleshooter has failed to diagnose the issue each time I've run it.Possibly related - for several days now, whenever I shut down my PC, I get a pop-up that says "Task Host is stopping background tasks. \Microsoft\Windows\DeviceDirectoryClient\RegisterUserDevice."This is driving me bonkers - any help would be hugely appreciated!Edition Windows 11 HomeVersion 24H2Instal

Hi, some history please (so often omitted by posters):
- when did you last successfully update this PC? (I.e. how new is this problem, noting you're on 1909).
- have you done anything specific to block Windows Update to stay on 1909?

If you look at your Update History (screenshot please) that will show which update (or feature update- upgrade) is failing.
