Hi, Matthew! It's my pleasure to assist you with this today.

Kindly try to do these steps and check if it will fix the issue. Thanks!

Let's try to enable the QoS tagging on this console.

Please go to Settings and select General > Network settings > Advanced settings > QoS tagging settings

Enable both the DSCP and WMM tagging

Reboot the console

Then press and hold the Power button on the front of your Xbox until the console turns off.

Unplug everything from the back of your Xbox.

Wait 3 minutes, and then plug the power cord and HDMI back in.

Let me know if that works. Thank you!

I’m playing on Xbox one series X, and no error codes just dashboards to the Home Screen

On a second glance I think it is a error in the demo it keeps shutting down my console at the exact same part please tell unreal and epic to fix they're stuff or xbox should take this demo into they're own hands it's extremely disappointing that I can't play this I just got a xbox series x probably exclusively because of this demo please fix this demo one way or another
