Hopper glitch-game crash

One of the players in my world created a hopper system for chickens and their eggs load into a chest. This chest originally glitched every time you clicked on it, the beta app freezes and then crashes. I no longer wanted the hopper and so I tried to get rid of it. I set the chickens free from the hopper chain and glitch remained. That player suggested taking TNT and blowing up the hopper system. The TNT blew up the first time and the game crashed, just like before. Now whenever I log into that world, the TNT is lit and proceeds to blow up. After that the entire app crashes and I have to reload the app. I am really new to this game and so I trusted this player since he has been playing the game for a few years now. I cannot load this world anymore and I have made so much progress on it already. Please fix the PE Windows 10, I've already lost a world because of this terrible app.
