Game crashes!!!

I am playing minecraft pocket edition on Bluestacks as a OnePlus mobile phone.
I cannot play my minecraft all. Everytime when I try to create a new world and try to change the gamemode, the game just crashes. It happens when I tap on the gamemode button and when i come back into the game, there isn't even any crash report. Even if I didn't try to change my gamemode, the game just crashes straightaway when I got in the world. I see no one complaining about this so I wonder does this only happen to me.
