We're experiencing a peculiar issue where KB4538461 will fail to install when it's distributed via WSUS but install fine when manually applied via the .msu file from Microsoft Catalog. We're trying to install it on Windows 10 1809 machines.
Windows Event viewer is displaying the following:
EventID 20:
Installation Failure: Windows Failed to install the following update with error 0x80246007. <patch name>

The only consistent solution that allowed WSUS to install the update was uninstalling the Threat Prevention module from the client. On a few machines, disabling Access Protection would suffice. but uninstalling Threat Prevention yielded the most consistent positive results.
Does any one have any idea why this could be happening? There are no threat events being generated whatsoever. I tried to exclude the following paths but it made no difference: C:\WINDOWS\SoftwareDistribution\Download .
