Windows Defender Antivirus Network Inspection Service issues since Windows 10 2004 update

I got the 2004 update yesterday and that went well enough otherwise but I am having a problem with the Windows Defender Antivirus Network Inspection Service that I did not have previously. 

  1. I noticed in Event Viewer several Errors that began immediately upon completion of the update last night: 

The Microsoft Defender Antivirus Network Inspection Service service depends on the Microsoft 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.

  1. Further inspection has revealed that there is now a problem with Real Time Updates. 

Microsoft Defender Antivirus Real-Time Protection feature has encountered an error and failed.

  Feature: Network Inspection System

Error Code: 0x8007042c

Error description: The dependency service or group failed to start. 

Reason: The system is missing updates that are required for running Network Inspection System.  Install the required updates and restart the device.

I've got this error repeatedly (3002). 

  1. I went into security and maintenance to see what was going on with my security settings. That is not showing anything "wrong." 
  2. The Network Inspection Service is configured to manual, not automatic. I can't change this. 
  3. Real-time protection is on, and has been on. On Virus & threat protection settings, all of those are still toggled on, and those settings are the same before and after the upgrade. I haven't tried turning them on and off again yet. 
  4. I already did the August Safety scan, but I downloaded a fresh copy and am re-running it. 
  5. I did dism and sfc checks and they showed no problems that needed repair. 

Something is definitely wrong with the install of Windows Defender tho... Help? How do I fix this and stop the errors and get it reconfigured properly. Do I have to reinstall it?

    I am NOT using BitLocker.

    However, per posts above, there are indications that the driver for a Western Digital external hard drive is not compatible with the current MS Defender platform.  I have a WD external hard drive.

    This is something MS needs to fix.

    I'm wondering, are you also using Bitlocker on your system?

    The same here - tried to switch the Memory Integrity back on and was notified of the WD SES wdcsam64_prewin8.sys driver being incompatible with this feature. It was imported, though, into the system on July 24th successfully with the mentioned feature being "on"  back then. The driver version is 1.2.0.0

    PS This is a known issue https://answers.microsoft.com/en-us/windows/forum/all/core-isolation-memory-integrity-fails-to-enable/b5673d5c-f3ce-4f0d-89c4-0f6f60527883

    I posted this whole story on Microsoft Feedback

    No it doesnt have anything to do with Microsoft breaking Defender, but it may keep you from re-enabling Memory Integrity if they ever fix this, haha.

    If it does, you can open Device Manager, scroll down near the bottom and delete Western Digital SES somethingorother (on mobile atm and can't remember exactly what it is called), tick the delete from drive or whatever box it is, and then re-enable Memory Integrity if that is the only thing you have causing a conflict.

    It wont effect the functionality of your drive itself, though it may effect the functionality of some WD diagnostic software if you use that for your drive; I do not.
