NvTensorRTRTXExecutionProvider was not downloaded automatically by ensure_and_register_certified_async().get()

Describe the bug

I'm following these steps https://learn.microsoft.com/en-us/windows/ai/new-windows-ml/get-started?tabs=python#step-2-download-and-register-eps. After I ran this Python script, the NvTensorRTRTXExecutionProvider was not downloaded automatically by ensure_and_register_certified_async().get() (I have installed CUDA 12.9 and driver 576.88 on RTX 4090), but the NvTensorRTRTXExecutionProvider can be found by calling find_all_providers()

Steps to reproduce the bug

1. Installed CUDA 12.9 and driver 576.88 on RTX 4090
2. Following the steps in https://learn.microsoft.com/en-us/windows/ai/new-windows-ml/get-started?tabs=python#step-2-download-and-register-eps
3. Tryensure_and_register_certified_async().get()
4. NvTensorRTRTXExecutionProvider was not downloaded automatically.

Expected behavior

NvTensorRTRTXExecutionProvider should be downloaded automatically.

I'm experiencing this too, EnsureAndRegisterCertifiedAsync isn't downloading any execution provider components.

By using provider.EnsureReadyAsync() I can observe a Package was not found error for both OpenVINOExecutionProvider and NvTensorRTRTXExecutionProvider.

Perhaps the Windows Update delivery mechanism is down?

Interestingly, I can't see KB5072094 (OpenVINOExecutionProvider) and KB5068004 (NvTensorRTRTXExecutionProvider) on catalog.update.microsoft.com either.

Can you file feedback through Feedback hub under Developer Platform > Windows Machine Learning and provide a link here? If you can include repro traces that will allow us to diagnose what issues may be being hit in EP download/installation.

I have the same problem. Did you manage to find the cause?
