Microsoft Defender Advanced Threat Protection might stop running

22-10-2019 (Bron: Microsoft.com)

After installing the optional non-security update (KB4520062), the Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data. You might also receive a 0xc0000409 error in Event Viewer on MsSense.exe.
Note Microsoft Windows Defender Antivirus is not affected by this issue.
Affected platforms:

• Client: Windows 10, version 1809; Windows 10 Enterprise LTSC 2019
• Server: Windows Server, version 1809; Windows Server 2019

Next steps: At this time, we suggest that devices in an affected environment do not install the optional non-security update, KB4520062. We are working on a resolution and estimate a solution will be available in mid-November.
