Mouso core worker process

My computer (Windows 10, 64-bit Build 19041) is constantly waking up from sleep and then going back to sleep for a short time only to repeat the cycle.  I ran sleep diagnostics on the Windows PowerShell as administrator i.e. powercfg /systemsleepdiagnostics.  The report from yesterday (5/31/2020) indicates that my computer awoke from sleep 50-55 times during the course of the day until at about 8:00 p.m., I decided that it was better to fully shut down the computer rather than have these continued cycles.  The common thread in all these awakenings from sleep is MoUSO Core Worker Process (MoUsoCoreWorker.exe). 

- Power Requests

- \Device\HarddiskVolume5\Windows\System32\MoUsoCoreWorker.exe | START TIME | DURATION | TYPE | TOKEN | | --- | --- | --- | --- | | 2020-05-31T18:18:53 | 0:00:01 | Execution | 0xffff8389192ab2e0 |

This executable is a Microsoft programming element. 

 Why is this happening and what can I do to eliminate this totally annoying phenomena?

    After installing the latest updates (Aug. 11) on two PCs, the problem went away.  No requests.

    Given that the wake request listed in /requests is under the EXECUTION category, I'm curious whether this will help anyone else:

    powercfg /requestsoverride PROCESS MoUsoCoreWorker.exe AWAYMODE SYSTEM DISPLAY EXECUTION

    The /? for powercfg /requestsoverride implies that you can't add an override for the EXECUTION category but that appears to be false, you can add it and it will appear in the list. It's not clear to me yet whether it works, though, since other recommended workarounds in this thread have failed after a few days. I'll be trying it locally and it would be cool to find out whether it works for anyone else, as well.

    As mentioned on another thread, I installed the optional update KB4568831 which fixes the issue.

    I also manually installed KB4568831, but it did NOT resolve the issue with MoUsoCoreWorker.exe preventing sleep. If I want the computer to remain asleep, I have to manually Restart the Windows Update Service each time I boot or wake the computer from sleep. At least it sleeps nominally after doing that, but I'm still waiting for Microsoft to fix this problem.
