Every time I put an SD card in my camera, it says there is no card. I’ve tried multiple cards and it does the same for all of them. If I fiddle about with it enough it’ll work, but it’s not ideal as I do photos as a side job. Someone said maybe there’s a pin in the slot that’s bent. Can anyone help?

More often its just dirt. Have you tried just a very short blast of can’ed air? The connector assembly is part of the logic board and you will need to remove it to get to the contacts to check or to physically clean. A very big job!
