Broken After Update (Not Vibration Related)

After downloading the new (May 20th) update I cannot get Forza 6 to launch and load. It will launch and go to the screen where it shows your car in the garage and says press A to continue. When you press A nothing happens. I have tried 2 different controllers, updated the controllers, and used the controllers in other games where they work fine including the A button. Any ideas?

This happened to me earlier this week. It cleared up when I closed the Xbox app on my computer. Try shutting everything down and rebooting so that you see the green Xbox logo screen when the console boots up.

That was it. I was streaming to my laptop. All good now. Thanks for the help and my apologies for posting in the wrong section.
