What’s wrong with my Xbox

I left my Xbox on all night by accedent and now when it starts up it gives me a gray screen and my controller won’t work either.when it gives me the option to restart my controller stopes working and won’t let me choose the option to restart. I’ve tried a manual restart by holding the power button but it’s still not working. Was keeping it on all night the reason for this or is it something else because I have no clue
