Follow below steps to Disable DirectX Video Acceleration in Receiver.
 - Set Receiver local policy "Hardware Acceleration for graphics" as "Disabled"

Problem Cause

Exception is triggered while pointing to an invalid memory location. Last function on the call stack belongs to Intel and hence we are not able to load the parameters(Unable to Debug Intel Code).

Intel drivers are old and cannot be upgraded and they are running with latest version.

Whenever trying to open a session, the session comes up, but immediately crashes saying "HDX Engine stopped working" and all we can do is stop it and the session gets closed.

Please refer the article below to know how to disable hardware acceleration for graphics:
