[Bug]: AMF Encoder is crashing when used from Windows Service

[visuall]

Describe the bug Starting with version 23.2.1 of AMD drivers the SDK crashes when AMF Video Encoder Init method is called from a service.

Module that fails: amfrtdrv32.dll Module base address: 0x53220000 Failed address: 0x5324d0f8()

Exception thrown at 0x5324D0F8 (amfrtdrv32.dll) in XXX.exe: 0xC0000005: Access violation reading location 0x00000000.

As far as I can tell you are not handling properly the return from IDXGIAdapter::EnumOutputs which is DXGI_ERROR_NOT_CURRENTLY_AVAILABLE when in service mode.

To Reproduce Try to initialize AMF Encoder from a Windows service. It will crash with access violation in the Init method.

Reproducing here also, killing our product for any of our customers on AMD with this driver.
