It was also fixed with a definition update in Windows Defender some time last month, so you probably have the update since these happen in the background and don't require any restart. You can check by going to:

    C:\ProgramData\Microsoft\Windows Defender\Definition Updates\{BUNCH-OF-NUMBERS}

Right click `mpengine.dll`, choose Properties, click Details tab, and check to see if Product Version is >= 1.1.20200.3. Mine is 1.1.20200.4 and was updated in mid/late March. If the version is less than 1.1.20200.3, you can manually trigger a definitions update in Windows Defender under Virus & Threat Protection.
