Game crash

Good night!

I would like to report a game crash ocasion that happens when i enter in my world, the weird thing is that it only happens in one world (a survival one).

I doubt that is a RAM problem, even if the world have 16MB.

I don't code, but i think it may be a script problem, or colision, since i have a 15 x 15 blocks wide farm that contains large numbers of cows.

The problem started to happen since i installed the new version (1.16.20) and the moment i finished to build the farm.

Also, for a very strange reason, when i use internet connection the game won't crash for a brief moment, and the moment i enter the world, if i run, jump and move my head, it will, too, last for a brief moment before crashing.

I'm not 100% sure if it's the cow farm.

That's all, sorry about the long text, and some broken english, since i'm not a native american (or britain.... or whatever country that speaks english)
