    I wouldn't recommend the brute force disable of MoUsoCoreWorker.exe at this point. Sure, it will work, but I've never had to resort to that and multiple PCs sleep just fine. Arm hurts, so let's amputate it.

    I did have a similar scare where my PC wouldn't sleep for the same reason, but it turned out that it wasn't finished installing a Dot NET update. I think I just left it on for a while, then it finished, powercfg output was clear, and sleep resumed working again.
    Actually this seems to bring a memory from the deep ... I believe I recall having an install issue to the .DOT update back at the start of February. At the time, I managed to get the install finished and like you the problem "went away" and everything seemed fine, only to return in the last few days.

    Interesting. There was a Dot NET update last Tuesday on my PC. I wonder if you have it too or if it's causing this issue. I suggest you try the Windows Update Reset tutorial.

    I rebooted my PC to do a full backup ... I needed to one anyway & it gives me an option to restore my PC if something goes wrong.

    Upon reboot, waited about 2-3 mins and then ran Powercfg /requests and:

    EXECUTION:
    [PROCESS] \Device\HarddiskVolume3\Windows\System32\MoUsoCoreWorker.exe
    USO Worker

    Went WU and did a manual scan ... nothing found.

    Running these cmds now:

    sfc /scannow
    and
    dism /online /Cleanup-Image /ScanHealth

    Will update this post shortly with the results...

    1st Up SFC /scannow:

    PS C:\Windows\system32> sfc /scannow

    Beginning system scan. This process will take some time.

    Beginning verification phase of system scan.
    Verification 100% complete.

    Windows Resource Protection found corrupt files and successfully repaired them.
    For online repairs, details are included in the CBS log file located at
    windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
    repairs, details are included in the log file provided by the /OFFLOGFILE flag.

    The log itself is long but there's:

    Code:
    2021-02-19 16:56:11, Info                  CSI    000001fc [SR] Repairing 1 components

    2021-02-19 16:56:12, Info                  CSI    00000200 [SR] Repair complete
    I also notice that there's a cab file in the C:\Windows\Logs\CBS directory:

    CbsPersist_20210210035416.cab
    Date of: Wed, 10, Feb 2021, 2:45pm
    Size: 63mb

    No idea about this at all. Will check it later, too big for Notepad. Have to use Notepad+.

    The log itself has a date of the 9/Feb/2021 and *seems* to be about the monthly update.

    Moving onto the DISM cmd ... the last time I ran this cmd was under Win8.1 & I think it took ages but I then did a clean install of Win10 back in October 2020. Back soon.

    Win10 must be a bit faster:

    Code:
    PS C:\Windows\system32> dism /online /Cleanup-Image /ScanHealth
    
    Deployment Image Servicing and Management tool
    Version: 10.0.19041.746
    
    Image Version: 10.0.19042.804
    
    [==========================100.0%==========================] No component store corruption detected.
    The operation completed successfully.

    I'm hoping there's a stuck update that the reset will clear and yes, making a backup is always prudent.

    Check your Windows Update history for February CU KB4601319 installation and a .NET CU update around the same day within this past week.

    WU History has:

    2021-02 Cumulative update for Windows 20H2 KB4601319 successfully installed on 10/Feb/2021
    2021-02 Cumulative update for Net Framework 3.5 & 4.8 for Windows 10 KB4601050 successfully installed on 10/Feb2021

    Given that I'm in Australia that would be 9/Feb2021 US.

    Bazza,

    You seem to have overlooked that posted solution. It directly addresses your reported problem and it works.

    Chop the arm off because it hurts is not a good solution, Denis.
