A certain part of my survival world stoped working after 1 hour afk at my mob farm

A certain part  of my world stopped working after I stayed 1 hour afk at my mob farm, when I'm in there I cant close the game without fore quit it, and  every time i reopen the world I'm in the spot I was before going to the "broken zone". I mention that the rest of the map works normally, only there is not working, and by working there is: breaking stuff not appearing anything, if I enter elytra mod, I stay like that until I close the game and I cant interact with anything (chests, item frames, nether portals). The same issue appears if I try my world in other devices, I tried so many ways to solve the problem and I don't want to loose my progress there.

Update: The problem was caused by an excessive amount of entities, was solved using an tool that deleted them

I reopened the issue by mistake, the problem was solved
