Since this recent Patch client keeps randomly closing for no reason

So this hasnt been a problem with me before but every since this recent patch ive been getting my client crashing when im idle. seems like if i stay on my profile, or the store its ok, but sometimes when im waiting in a lobby or just on the main menu it always seems to crash! it isnt too bad since if im in a game it doesnt crash or anything, but just the client when im idle!
