Game Crashes after 30 seconds/during save and quit

Whenever I boot up my world in minecraft after a certain amount of time or whenever I try to save & quit the game crashes and says "The software was closed because an error occurred". This only happens to my one world that has a size of 52.8mb. After we beat the Ender Dragon and saved, the game has been crashing since. I tried making a new world and I was able to save & quit with no problem.

 

I have tried logging in and out of the minecraft account and reducing the chunks rendered but the issue still persists.
