Random Crashes, Overwork Crashes

Ever since the 1.16 update came out for Minecraft, I've noticed a lot more crashes. I could just be idling my PC and Minecraft crashes. I haven't noticed anything like this on my iPhone because I don't play as often on it. I also get crashes on worlds where I fly too fast in creative above lots of builds. The builds have no active redstone inside of them. This is by far the most annoying bug I experience. I think it's due to my systems trying to load chunks too fast and they just don't load. This crash happens to my PC and my iPhone.
