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).

This executable is a Microsoft programming element. 

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

    I manually ran my windows updates and got a cumulative update that fixed the issue. 

    What was the KB?

    I think it is still worthwhile to keep this discussion here. I thought my issue was with MoUsoCoreWorker.exe because that's what I saw in the powercfg.exe output when the display would instantly wake back up from the sleep that was just started. However, this was a red herring, at least for me. The real issue was the USB device. I discovered that because of a suggestion in this thread.

    After initially observing the MoUSO issue in play via the powercfg CMD, I tried ALL of the suggestions in this thread with no success. 

    I have just tested an application I have running on my PC called GoodSync, which runs in the background and at allocated times runs back up jobs.  I turned of the scheduled back up and YEAH, computer slept as per settings.

    Turn back on schedule, no sleep.

    It is suspicious that this problem started happening at same time as the update that cuased the MoUSO issue but I can say for sure it is related because I just do now.

    Not helpfully Goodsync support says:

    GoodSync receives wakeup signall all the time.

    and it does not generate it itself.

    so GS has nothing to do with this -- find a real source of wakeup

    I replied 

    Hi William,

    Thanks for the reply, however (with respect), your answer does not respond to the question.

    Even if GS does not generate wakeup signal, GS IS WHAT IS STOPPING THE SLEEP.

    When GS is set to "On Schedule" & "Run without User Interface (Unattended)" my computer does NOT go to sleep.

    When GS is set to NOT Set to "On Schedule" & "Run without User Interface (Unattended)" my computer DOES go to SLEEP.

    GS is the only thing that changes the result from no sleep to sleep.

    Please think about / look again or pass this issue on to another tech

    Its not solved but I hope this helps someone .

    Thanks, worked for me. Just wondering, if I set it back to manual again, will I get that process error with every next update?
