I have a world in which I've finally found a fortress and wanted to get ready for it, so I went to my iron farm to get some iron, but that's not important. What's important is that after I went to the iron farm (through a portal) the game crashed instantly when I entered the overworld. I tried to load the world again and when I did I found my iron farm large chest half invisible so only one small chest shows and the other one I can only see the hitbox. I tried to open the invisible one but the game crashes. I tried a few times and it always crashes. So I ignored that and wanted to go back home and what I haven't expected happened. The world just froze. I can literally do nothing but walk. I tried breaking any block but it just breaks the block and doesn't drop anything or doesn't show the breaking animation. I tried killing a pig nearby but nothing happens, it is just freezed. I even tried to open a furnace or open my inventory but nothing happens. I tried to go back home to see what happened and the chunks aren't loading anymore, my world just froze... This world is corrupted (I think so I'm not sure) which is very annoying since I made a lot of progress in it. Also by the way I got all of the bugs that are in 1.16.100 including the villagers floating bug, the chunks not loading, delayed (or sometimes no) breaking and picking up items, and the saving game screen is loading forever. So plleeaassssssse fix those bugs because I am not playing Minecraft any more until those bugs get fixed (so I won't lose any more progress). And thank you so much if it gets fixed.

Here is a video to help. I made it a link on Youtube because it can't fit here. https://youtu.be/vonn1Ju_nys
