When playing on a friend's world in multiplayer, either of us opening a shulker box will crash only MY game. This happens maybe 25% of the time a shulker box is opened. It doesnt matter what shulker box is opened, what is in it, or where it is located. I wish I could share more details but it is rather inconsistent and any photos would just be an image of my screen frozen in place. The only thing I can do when this happens is close the game from the taskbar and then reopen it. It is worth mentioning that I have only had this problem in 1.16 and above.
