I can't open up Forza 5

I just can’t open the game when i put in then disk, i click on it multiple times but nothing happens. HELP!

Hard restart the console (cut off instant on). When it cuts off, unplug it for a few seconds. Plug back up & cut on. Should be fine. I have never had that exact problem before. But I noticed with instant on, that before turning off console, if you go to home screen dashboard & just start hitting B button, console will cycle through all junk running. I hit B button till the only thing it’s doing is going back to the video game.

I haven’t had to fully power off my console no more and can leave on instant on with no issues.

I know EXACTLY what you are talking about… HINT - switch controllers. It works for me every time. I have found that FM5 seems to link directly to whatever controller was last logged in to FM5. I figured this out because I sit in one spot and use one controller most of the time. My son sits in another spot and uses another controller. 95% of the time this happens to me its because he was playing that day before me. I switch to his controller but my xbox sign in and it fixes it every time. I dont know what causes it to only see the one controller as primary but it happens a fair amount to me. I would say once per week.
Thanks
