I was playing on my creative world dying leather boots in cauldrons and then putting them into shulker boxes, when suddenly I tried to dye one of the boots and it wouldn't do anything. I kept pressing use and soon realized none of the animals were moving and I also could not interact with the shulker boxes. I could still hear audio like the game was working. I broke a few blocks and they just vanished. No particles or anything. It started lagging really quickly so I panicked and saved the game before it crashed. When I went back into it, the game froze up again and I ended up having to shut off my pc to close the app. I tried re-importing the world and it did the same thing. Also, the image for the world in the world menu is the missing texture block. I'm very frustrated. I did update my PC as well, and that did not help. I can't take a screenshot inside the world because it keeps freezing, but I included the missing texture.
