This issue affects people who have received the new Experience Controls update, which I have, and it is broken when changing the device to Xbox in the Test tab.
Below is an attached video which shows the issue in action.
You can reproduce this issue if you have the new Experience Controls, and then by selecting your Device as Xbox. It breaks the menu, and makes it impossible to leave the game without stopping it in studio.
I am unsure if it works on Windows, as the only machine that can access studio that I have access to is an M2 Mac running Ventura.
It has been 2 weeks as of this post being put up, and I am happy to report that the new Experience controls are now indeed working, but they have a few bugs to squash before they’re ready.
I’ve gotten access to a controller, so I was able to test a little more than checking if the ui works.
