Recently when I was in the playing of Yo Kai Watch 3, my game crashed with a message of "An error has occurred, please power down the system" or something along those lines. This was a bit concerning to me, although Yo Kai Watch 3 is a buggy game. I then switched to playing Mario & Luigi Dream Team. I was in the middle of an arena battle when my game stopped suddenly and displayed the dame error message below. Both my games are digital, and I was playing on my non-cfw old 3ds xl. Considering how this happened to 2 different games within the same time period and how both had no reason to crash, I have reason to suspect that my SD card is having some troubles. As a precaution, I've already gone ahead and copied all the files on my SD card to my computer. Upon inspecting the SD card slot I found a singular hair in there, although I doubt that it was the source of the issue.
