Microsoft Defender (nee Windows Defender) throwing error Events 7000, 7001

This was just posted by @glnz:

Windows Security [Microsoft Defender] has started throwing error messages in Event Viewer, in both 1909 and 2004, apparently in the latest Defender Platform 4.18.2007.8:

Event 7001: “The Windows Defender Antivirus Network Inspection Service service depends on the Windows Defender Antivirus Network Inspection System Driver service which failed to start because of the following error: The supplied user buffer is not valid for the requested operation.”

Event 7000: “The Windows Defender Antivirus Network Inspection System Driver service failed to start due to the following error: The supplied user buffer is not valid for the requested operation.”

The only fix found so far is to disable Core Isolation and Virtualization Based Security, by going to: Windows Security->Device Security->Core Isolation->toggle off memory integrity. Then, on reboot, the above errors stop.

This is discussed in two places:

Are you seeing the same thing? Thoughts?
