   Talked with some folks over here and this is expected! The runtime compiler is going to have the older validator from the preview release we did back in April. The fix from the previous issue came later so I'd expect this to continue to fail until the AgilitySDK is updated

   It should be possible to bypass the validation per https://microsoft.github.io/hlsl-specs/proposals/infra/inf-0004-validator-hashing/#d3d-debug-layer-validation-control

   Here is a snippet from copilot that has not been validated but should point in the right direction

   D3D12_DEBUG_DEVICE_BYTECODE_VALIDATION_MODE mode =
       D3D12_DEBUG_DEVICE_BYTECODE_VALIDATION_DISABLED;
   
   ComPtr<ID3D12DebugDevice1> debugDevice;
   ThrowIfFailed(device->QueryInterface(IID_PPV_ARGS(&debugDevice)));
   ThrowIfFailed(debugDevice->SetDebugParameter(
       D3D12_DEBUG_DEVICE_PARAMETER_BYTECODE_VALIDATION_MODE,
       &mode,
       sizeof(mode)));
