On my mac computer, I cannot create a new world or join an existing one in 1.14 without my game crashing. This does not happen in 1.13.2, or earlier versions. If I reload, there still is no world.

happens to me as well, but only if i have cheats and bonus chest enabled. if i load the world after booting minecraft back up, bonus chest does not appear

It happens even when I don't have those enabled. Also, the word doesn't show up after a reboot.
