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'd like to update that I had tried the KB4568831 patch prior to August 11's Patch Tuesday with no effect (computer would not sleep by itself, nor stay asleep when manually done). MoUsoCoreWorker.exe continued to show in powercfg /requests .
But after 3 days since August 11's cumulative patch, my computer has slept and stayed asleep by itself.
After the Aug 11 updates (2nd Tuesday monthly), the MoUsoCoreWorker.exe process is no longer showing up under powercfg /requests. And, if I put my computer into Sleep mode, it stays that way. But, it still will not GO to sleep after xx minutes idle. I just tried the KB4568831 fix, but I get a message: This update is not applicable to your computer.
Update - Aug 18, 2020
I discovered that when I unplug all USB A/V devices, the computer goes to sleep as expected. With those devices plugged in, powercfg /requests always shows their drivers as active. This is new behaviour which began with Feature Update 2004.
I tried (as someone in this thread suggested) powercfg /override, but that did not work for me. I have to physically unplug the USB devices - really annoying.
The KB4568831 update fixed my computer. Three days now of good sleep.
Same for me.
It has for me as well.
