MC-160789Instant game crash when joining world while paused
I am exploring in a boat, the teacher is coming so I quickly quit Minecraft. When he leaves, I try to get back on but the game crashes as soon as I load the world. It shows me in the boat then crashes. Do not say anything about karma. This only happens when I immediately open the game menu when joining
Here is the crash report:
