Currently, this function is passed through winevulkan to the system's Vulkan loader, which causes the loader to write the system's device layers properties in pProperties.
Unreal Engine 4 then calls vkEnumerateDeviceExtensionProperties, using VkLayerProperties::layerName as the pLayerName.
winevulkan's implementation of vkEnumerateDeviceExtensionProperties then returns VK_ERROR_LAYER_NOT_PRESENT, crashing UE4.
This issue was found while debugging Project Wingman (Steam appid 895870), but it should also happen to any UE4 application using the Vulkan RHI.
