UE4 Crashes in FVoiceModule

I get a similar/related error “Exception thrown: read access violation. lpGuid was nullptr.”

#if PLATFORM_SUPPORTS_VOICE_CAPTURE
	if (bEnabled)
	{
		if (!InitVoiceCapture())
		{
			UE_LOG(LogVoice, Warning, TEXT("Failed to initialize voice capture module"));
			ShutdownVoiceCapture();
		}
	}
#endif
}

Error is being thrown in VoiceModule.cpp in line 38 → “if (!InitVoiceCapture())”
