Yo-kai Watch is not working anymore?

Ar

Since I'm an Otaku, I also have games, DVDs and so on. So also two Yo-kai watch games for the Nintendo 3DS. There have been no problems with the games so far. Today I once again played Bony Ghosts. Because of a feature in the game, I wanted to use the other, first Yo-kai watch game. I have done this as usual. First saved and then taken the card. But the first game can't be started at all. Each time it crashes during startup and then comes an error message that the system needs to be restarted. Every time. I do not understand why, because neither the Nintendo nor the game itself have somehow fallen down or broken. The last time I played the first game was a while ago, but at the time it worked without any problems. I don't understand what's going on. Can someone help me please?

Are you an Otaku, a couch potato (Taku = house) or rather a nerd? - To my knowledge, Otaku is rather pejorative in Japanese, but that may be different within pop culture.
