I was loading into 1.16.3. I clicked "Presets" and changed the preset of the new world that I was making, and my gamed crashed. I did it again, and the same thing. Then it crashed when I try'd to go out of fullscreen.

     Hey, This morning, I was loading 1.16.3, because I saw it had come out. I was making a new world, and then I was changing the preset to iron blocks, and then when I hit "use preset" the game crashed. So I loaded it and try'd again. Same thing. So, I loaded my game again. It was doing this glitch that it always does, where I have to click each button 2 times (I'm on a mac). So I normally go out of fullscreen and back in and it fixes it. But, when I hit the button to go out of fullscreen, it crashed again.

Just thought I should report this.
