Chosen Solution

On my Nintendo 3ds Xl, after playing around 5 minutes of a game, the console goes to the home screen with this message “An error has occurred, forcing the software to close” and I lose my progress. Usually happens when a pokemon evolves or in trades in pokemon Y or pokemon omega ruby. I’ve already tried to resetting the console and replacing the sd card, the games I’m having trouble are physical copies, but I tested them on another device and they worked fine.

Hi! This sounds to me like a problem with the game card reader. Use a flashlight to get a good view of the pins inside of it. If one of them is bent or out of shape, try bending it back in place. If everything seems alright, grab some Q-tips and some isopropyl alcohol and try cleaning them up. If none of this works, you may need to either replace the reader or the motherboard as a whole.
