Game froze and now xbox wont turn on

Hello, I’ve been playing since release on my xb1. Since then I got Flak to 50 and just started my Amara. Ive had no problems until yesterday when my Amara ran past the slaughter shaft I decided to try it since I skipped it my first playthrough. During it my game froze and I had to shut off my xbox. Now whenever I try to turn my xbox on the light comes on for about 15 seconds like its trying to turn on but then it just shuts off. Ive tried holding down the power button, unplugging it for awhile. No matter what I do its the same and Im out of ideas. Can anyone help? Thank you.
