New Qualcomm machine being picky about using SetDescriptorHeaps before setting a root signature

[Icohedron]

The new Qualcomm machine is failing OffloadTest-warp-d3d12 :: Feature/RootSignatures/Flags.test due to being picky about using SetDescriptorHeaps before setting a root signature.

This should be a function of the d3d runtime, not what hardware is being used. Any idea why this is only impacting one machine?

I'm actually not sure why.

Are all the machines running the same OS?

Are all the machines running the same OS?

All the HLSL machines in the lab are running Windows 11 Pro 24H2.
Though the AMD and NVIDIA machines are using build 26100.6584, while the QC machine is using build 26100.6725
