Game crashing in Nether

The game is crashing when going further than 100 blocks in the nether, I cannot produce screenshot as it goes to the home screen and goes back to a couple of blocks back in the world and recoours.i have produced a screen video that highlights the game crashing twice. 

 

I have lost a world to this issue as I unistalled and reinstalled the game and in the new world it is crashing, this is done is survival mode. 

 

This prevents me accessing new bimoes and getting to a fortress or bastion and completing the game.
