My Minecraft crash after using a dispenser

How to play:
1. Place a Dispenser on the ground with 1 pack's bone meal inside It and make a grass platform above it with 3x3
2. Now connect the Redstone Dispenser to a redstone source (lever, redstone torch, redstone block. Whatever)
3. The chashs game

Expected:
Expected is the game not freezing simply because there is a working Dispenser
