WebXR broken

So sometimes I see this update notification in my Hololens 2 device, and as a nice user I do it. And usually this is when things start to stop working as they were.

Today it's about https://immersive-web.github.io/webxr-samples/ that do not work anymore for immersive-ar sessions or immersive-vr sessions. According to this post it's been broken for some long time, and it's probably related to some Microsoft Edge update.

The error in the developer console of Edge has no details, it just says "XR Session creation failed: the specified session configuration is not supported."

Any MVP feedback on this would be very much appreciated please.
