Hello, today after the 1.16.221 update, I entered one of my worlds, however before I could, the light went out, after 1 hour I was able to enter the world again, but to my surprise, the world was completely destroyed, with holes everywhere, of the size of a whole chunk, and with glitches in the menu, up to the point where a data folder with the name 'lost' appeared along withthegame files. Does it have something to do with the recent hot fix or is there a way to solve it?

I don't have many images but I was able to get the image of the World Icon, and you can see more or less of what I'm talking about. The reason why I don't have images is that because of my fear of losing it completely I restarted the game to try and recover the world, since at the beginning it seemed as if it did not load well yet. The world was so corrupted that the water and lava were flying until you put a block next to them, which is when their physics started to work.
