Hi and welcome to Android forums.

Remove the SD card and see if the phone has any issues when the SD card isn't installed. That way we can rule out the phone being a factor. If you can, try another SD card in the phone and see if the new SD card is readable.

Can you remove the SD card and try it in your computer to see if it is readable? It might be that some data on the card is corrupted and if you don't have any data on there that is vital, your best bet might be to try a format via a computer.
