Cannot Create A world and cannot go into the settings of my worlds

Whenever I try to create a world my minecraft freezes for 2 seconds and then the screen goes black and next thing I know I'm looking at my home screen. Same thing happens whenever I try to go into my minecraft settings on the home menu or if I try to go into my minecraft settings while I'm in a world. I cannot create any new worlds or change or access any of my settings. Please Help.
