If you are using any GPO check the below points:
Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment
Then enable “Use the hardware default graphics adapter for all Remote Desktop Services sessions”
Update the Group Policy
