Start with Samples/WindowsCopilotRuntime and reproduce the LanguageModel or Image Description flow on the Intel 200V platform and OS build 26120.3281. Inspect the IsAvailable and MakeAvailableAsync calls around the reported COMException; done means establishing the cause and supported behavior for this platform and build, with a fix if required.
