New CFexpress card not working

Just bought two new 128gb Sansdisk CFexpress B cards for my Nikon Z6ii’s, as soon as I put them in the camera’s it gives me an error “card is not formatted”. But the option to format them is blank on the camera’s, as they’re new and have no images on them.

Am I doing something wrong, or are both my new cards faulty?
