My minecraft keeps crashing ever since the new 1.9 update was released.

So with the realease of the new 1.9 update my minecraft keeps crashing. It will sometimes let me open a world and play it for a bit and then crash, and at other times it will crash upon me trying to open a world.I have completely deleted and reinstalled my minecraft twice and it still keeps crashing. I have attached the message it keeps reporting when it crashes.
