My Ender 3 Pro does not read my sd card

Hello, had my printer in storage, I brought it out and upgraded a few things (Nozzle, struder). I put the sd card in to do a print and the printer is not reading my card. I have no idea why. I have tried formatting the card and tried different sizes of it and it still does not read it. Has any one experience this and has fixed it?

If its been in storage for a while it might has a build up of dust in the slot, try blowing some air into the slot, not to much pressure though
