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?

    It help's for me for a while, but today (sep. 4th 2020) I've noticed same problem again. I have KB4568831 installed.

    Like JanezTroha, installing KB4568831 worked for a few weeks with no problems but I rebooted my machine yesterday after the latest updates and it is now being kept awake by MoUsoCoreWorker again!  I will reboot again later, but it seems the problem may be back again!

    I have automatic updates disabled in Group Policies. On August 20 I checked for updates and applied them. Ever since then the system would not go to sleep at the proper idle time interval.

    powercfg requests revealed:

    EXECUTION:

    [PROCESS] \Device\HarddiskVolume7\Windows\System32\MoUsoCoreWorker.exe

    USO Worker

    Update status showed no updates pending and all updates installed completely. Stopping in starting Windows Update Service did not stop the request.

    Issuing the command:

    powercfg /requestsoverride process mousocoreworker.exe execution

    would allow system to once again sleep at idle timeout. However powercfg still showed the request.

    I then ran the Update Troubleshooter which reported no problems, nothing to fix.

    I shutdown the system. Waited a few minutes and restarted.

    powercfg requests showed the request was gone and has remained gone after several restart.

    It appears Update Troubleshooter stopped MoUsoCoreWorker.exe perhaps in combination with powercfg /requestsoverride.

    Should I allow it? I am not so sure if this is good since it's an executable file.

    Sorry to burst all your bubbles but my computer is updated and it still won't sleep and MoUsoCoreWorker.exe is the culprit.

    My other computers never had the issue so it is not effecting everything.
