Game crashes when using locate command

When I joint a new world I tried to use the locate command and i got the coordinates. But  when I tried to teleport the game crashed. I tried joining the world again and the game crashed again. I made a new world and I was able to join but when i use the locate command again, it was like unexpected error and some minutes later the game crashes again. Please fix this bug.

Sorry that I did not pay close attention to the crash reports i attached but here are the crash reports which occured when the 18w48a snapshot came. Hope this helps. Thank you.
