Warzone opens and closes immediately?

I have tried everything for the past 3 hours and I cannot open my warzone game…I click on it and it opens for 1-4 seconds and shuts it down and closes it again and again…ANYONE have any options to help??? Thank you in advance!

You’ll need to contact Activision Support for that type of an issue… see: Having Problems with Call of Duty? Read this first! for details.
