Windows 2019 Server RDS stops working after a warning event of DWMINIT

Question

Hello Support,

Windows 2019 Server RDS stops working after a warning event of DWMNIT. Until the server restarts, the RDP does not work. Any technical advice would be great.   

This is what event viewer looks like during or around the time of a crash:

Hi, Dhananjaya M

This is Chaboon.

I seem, this problem seems to be caused by the driver for your display adapter, not by Windows.

see below article, and you should be update your display adapter's driver newest.
