[MC-198414] if the angle in /spawnpoint is set to +-infinity, and the player dies, it will kick the player, and upon rejoin will crash the game

The bug

If you set a player's spawn point angle to +-infinity (/spawnpoint @s ~ ~ ~ 999999999999999999999999999999999999999, it will show up as NaN in chat) and then let the player die, it will kick the player with an "Invalid move player packet received." Trying to rejoin the world will crash the game. This also permanently locks you out of your world.
