D3D12: `d3d_D3D12GetInterface` with `CLSID_D3D12DeviceFactoryGodot` returns `E_NOINTERFACE`

[ghuser404]

Tested versions

Custom 4.5.dev2

System information

Godot v4.5.dev (f265ae177) - Windows 10 (build 19045) - Multi-window, 2 monitors - Direct3D 12 (Forward+) - dedicated NVIDIA GeForce RTX 3060 Ti (NVIDIA; 32.0.15.7283) - Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz (8 threads)

Issue description

There is this code for dynamically loading newer D3D12 functionality

if (SUCCEEDED(sdk_config1->CreateDeviceFactory(agility_sdk_version, agility_sdk_path.ascii().get_data(), IID_PPV_ARGS(device_factory.GetAddressOf())))) {
	d3d_D3D12GetInterface(CLSID_D3D12DeviceFactoryGodot, IID_PPV_ARGS(device_factory.GetAddressOf()));
} else if (SUCCEEDED(sdk_config1->CreateDeviceFactory(agility_sdk_version, ".\\", IID_PPV_ARGS(device_factory.GetAddressOf())))) {
	d3d_D3D12GetInterface(CLSID_D3D12DeviceFactoryGodot, IID_PPV_ARGS(device_factory.GetAddressOf()));
}

Looking at the debug logs, this line SUCCEEDED(sdk_config1->CreateDeviceFactory(agility_sdk_version, ".\\", IID_PPV_ARGS(device_factory.GetAddressOf()))) loads D3D12Core.dll for the specified location, but the next line d3d_D3D12GetInterface(CLSID_D3D12DeviceFactoryGodot, IID_PPV_ARGS(device_factory.GetAddressOf())) also loads D3D12Core.dll, but from C:\Windows\System32, and returns E_NOINTERFACE.

Steps to reproduce

1. Set d3d12 renderer for you app
2. Debug the _init_device_factory function
3. Observe the logs when calling d3d_D3D12GetInterface

@DarioSamo I see the initial implementation was from you. Maybe you have more information?

Can you test if this happens in 4.4.1?
