The reason for the game quitting is because the processor isn't made for gaming. Also an i3 isn't really recommended either. The game recommends an i5 or i7 processor to have the best overall gaming experience.
These types of laptops with U processors aren't designed to play games. They're more made for office/homework, watching videos listening to music and other light tasks. Not so much for gaming.
Without getting too technical, they make the U (Ultra-low-voltage or UVL) processors to save energy/electricity to help save battery life. But they do this at the expense of the processing power games need. So it makes for a not so good gaming experience.
