Unable to log back into Warzone

I played Battle Royal logged out for about 15 minutes came back to instant crash at the Activision video log in screen. Spent 3 hours reinstalling the game, got it played a few different games of battle royale then party members had problems everyone decided to reboot the game … wooolah AGAIN intant crash cant log back into the game… I am not going to uninstall and reinstall every time I want to play the game??? Beta ran better than this wtf going on? What can I do other than uninstall again?
