hoping for a quick reply relying on you

Most likely the card is defective. You should contact SanDisk for a warranty replacement. Unfortunately, there’s nothing to be done about retreivinig your files fom the card, unless you want to pay a professional data recovery service a few hundred dollars to attempt to get them off the card (which isn’t guaranteed).

how I apply for replacement
