Constant Errors, Unable to load world

Minecraft is unplayable due to the constant error messages that I receive which states " Software closed because an error occured " This happens when I try to create a new world or join a world. Sometimes I will spawn and walk around then the error appears shortly. I have done everything from checking corrupted files , re - installing as instructed on the nintendo website, deleting minecrafts data and formatting the sd card. All are working okay. Minecraft just seems to be unplayable right now for me and I am dissapointed. I should mention that I have the digital edition of the game.
