Weird issue with streaming to a Win10 laptop

Hi there,

Of late, I've lost the ability to stream to my Win10 laptop. For context, this is how I play the majority of my time and have done for a number of years. My Xbox One is visible in the app. It allows me to connect and initiate the steam function but after
the initial stream page rolls up it never actually gets to the Xbox screen. I just get the transparency of the app.

Things that are relevant:

Both the xbox and the pc are wired connections.

I'm in the Alpha Skip Ahead preview ring.

I've tried hard resetting both the Xbox and the PC, also both are up to date as of this morning.

The settings on the Xbox are set to allow streaming and connection from any device.

I've tried it with both the usual and beta Xbox app and I get the same result on both.

The stream test function returns four red "x"s, whereas previously I've used the "very high" setting without issue.

To emphasise; this is a new problem. I've streamed hundreds of hours of gaming with this exact set up and as far as I can tell nothing has changed from my perspective. Unless there had been an update to either the app or the Xbox?

Hope someone can help.

Thanks,

Dom
