My shadow doesn't start

My shadow was going well until playing warzone I hit a pull and removed the game re-entered the warzone but the same thing happened to me pull and it was removed from the game until I decided to restart the shadow l I have restarted and now is when it does not start it gets stuck in starting and so I have been two or three hours until I have opened a ticket and I have tried some things that I have read in this forum but nothing works for me.
