After changing camera ratio from camera option in third person char. game started crashing

Game crashes when opening level 2

Everything was working fine.build was running excellent but i wanted to make game for android in portrait mode so i choose portrait from android setting and changed camera ratio to .05625 from third person character bp and game is crashing now.i am sure if i undo ratio i think it will run as it was running in my last build.
So why this is happening??
How can i change camera ratio in portrait mode??

I have two levels in game first on is for play and select character after selecting char next level opens but due to recent modification game crashes during opening of level 2.
