https://drive.google.com/drive/folders/1s_xLLeXyCNRJmyem2vkqLd-g9XnU3DZm?usp=sharing here is the link of pictures and videos to my problems.
To describe it in words, my camera nikon d3500 is going half way click to autofocus but on full click is not taking any picture. Sometimes it shows error that Error. Press shutter release again. Even if this error is not displayed but still my camera is unable to take pictures.
I tried resetting the options but retouch menu is all greyed out, the reset menu in shooting menu is also greyed out. I also tried formatting the memory card and take the battery out for about 8 hours and re-insert it into the camera to reset the settings, but that did not work.
