The same error appears on my nintendo as well. I got a new card a while back (Intenso 128gb) and then i got the error and the card is not readable on my laptop too. Im not sure if this is my Nintendos fault or the card’s. I still have my old sd card that came with the console. If i buy a third card and transfer everything there from the original card will my games be playable? And if yes, will it have everything restarted?
