No output with OpenXR application

[jsemeda]

I am developing an application using OpenXR with Vulkan under WIndows10. The application is running but there is no output to the headset, shows a "waiting" sign. I ran the HelloXR sample and I am getting the same thing, runs no output. I ran the LoaderTest application from the SDK and here is the output report ...

I am not sure how to interpret the results, some thing have failed apparently. Can anyone see if there is anything here that can explain the failure to produce an output to the headset?
