Getting an error message when trying to launch a packed game

[Saito_Wind_Lord]

Everytime I launch the packaged, this error pops up:

LowLevelFatalError [File:D:\build++UE5\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12Util.cpp] [Line: 991]
RayTracingDevice->CreateStateObject(&Desc, IID_PPV_ARGS(Result.GetInitReference())) failed
at D:\build++UE5\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12RayTracing.cpp:663
with error E_INVALIDARG

Crash in runnable thread Foreground Worker #0

---

If I ignore it, then I can play for a little bit, but then it crashes at some point.
I’m not sure what the problem is, can anyone help please?

Greetings @Saito_Wind_Lord

Welcome to the Unreal Engine Forum. Does this occur if you run the project in DirectX 11 instead of 12?

[SerkanAyhan1973]

Same problem. Switching to directx 11 solves the problem.

[FrostyJas]

Right on! Well, I’m glad you found a solution! Does running DX11 work with your project? (Nothing requiring DX12)

[Saito_Wind_Lord]

Thx, switching to DX11 worked!

[FrostyJas]

Awesome! I’m glad that fixed it! Have a good week!
