I inserted the SD card on my mac and it doesn’t recognise, doesn’t even appear on disk utility. But if I have the card inside the camera and connect the camera via USB then I can see in disk utility that it somehow recognises a 16GB drive but it is not mountable or readable. This is also the only way photorec/testdisk detects the card. It didn’t when inserted in the SD card slot.
I tried first using the photorec/testdisk with no success. I’m not even sure which one I should use but then I understood I could try to format the card and then use photorec to recover the photos.
But then I figured out I can’t even format the card. Not in camera and not anywhere else.
I even tried using the app SD Card Formatter to format it, but I get this message:

Here is the log for testdisk:
