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?

    I can concur, this is literally what mine did too, right down to the pending update being KB4570721.  No more USO request in powercfg after installing.  I seem to remember something like this happening with Windows 7 a few years ago at work, had to do it on like 5 or 6 different computers.  Always seems to be a .NET update that causes the issues doesn't it.

    Same here, same update number too, only came available after stopping and restarting the Windows update service.  Was preparing for another S3 battle as per the last 10 years but hopefully all OK now.

    Interesting. So the consensus is that updates "stuck" in the background waiting to be installed are the cause of this.

    Since a couple of days, I have this same problem and when installing KB4568831, the system says that this patch is not applicable for this system.

    Windows 10 version: 2004

    OS Build: 19041.450

    @microsoft, when is this being solved, because now my computer never goes to sleep.

    My PC with this problem got an update and for now is fixed and enters sleep mode correctly.  Hopefully it'll stick.

    There's nothing listed with the "powercfg /requests” command.
