Motorola Moto G — Momery card?

Hello, I have a Motorola g7 plus. Here is if I take a photo I do not see it nor in google photos. The folder they go to is on the memory card. When I change the stokage folder for the phone it works, I see the photo. So I conclude that my memory card is defective. If I change my memory card will I solve the problem? How do I see if there are other things on the map? Thank you very much.
