I keep crashing in some of my servers but i think that this might be because of the new update

I was playing sky block, a survival and a creative server so i was just running around building and doing whatever i felt like doing until out of no where my game just crashed over and over when i was playing and some of the people were playing and they also crashed but thought that it was just them but all of us joined back and like 300 people said that they crashed.
