Azure ATP on Windows Server 2019 is now a certified and supported configuration! This support requires the installation of KB4487044 on servers where the Azure ATP sensor is installed.
If you have installed Azure ATP sensor on an unpatched Windows 2019 Server in the past, the sensor will automatically turn itself off. Azure ATP will automatically turn itself back on once the sensor detects the server update is installed.
