Cumulative update won't install (KB4571756) (Error 0x800f081f)

I am running Windows 10 Home 2004 (Build 19041.450). Windows Update notified me that there was a cumulative update available to install (2020-09 Cumulative Update for Windows 10 Version 2004 for x64-based Systems (KB4571756)). When I told it to install the update, it will download and go up to "Installing - 100%" and then just show this error: 

I've tried the following in an attempt to fix the error:

  • Run "sfc /scannow" in an elevated command prompt
  • Run "DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:<Source of clean Windows 10 2004 ISO created using Windows Media Creation Tool> /LimitAccess" in an elevated command prompt
  • Uninstall and reinstall NET framework 3.5 from "Turn Windows features on or off" in Control Panel
  • Manually download the specific update from the Microsoft Update Catalog and install it
  • Stop the Windows Update service and delete the Windows Update cache located in "%SystemRoot%\SoftwareDistrubution", then restart the service

Obviously, none of these worked so I'm looking for any other solutions to this problem. Any help is appreciated.

    Not a solution , merely workaround until next patch Tuesday, hide the offending update until resolved.

    Might be failing on certain hardware configurations (just a hunch).

    I did a chat with a rep and they assured me it should be resolved with the next update. Haven't seen anything come down yet on my system? Anyone else?

    Still not working for me.

    Last update that has worked for me is https://support.microsoft.com/en-us/help/4565503/windows-10-update-kb4565503 which was 7/15.
