My worlds still crash minutes after I get on the world!!!!!

After nineties and sometimes seconds after getting on one of my worlds, it crashes!!! This was supposedly fixed in the latest bug fix but I’m still experiencing crashes. I lose good progress on the world and I gets really annoying. It makes me lose in playing altogether if I’m gonna keep crashing, but I love the game so I play the servers I have access to. But the same stuff gets boring so playing solo survival worlds would be better.
