Cant connect to the Arduino Mega, port is not available

Trying to connect arduino mega , but port is not available, i tried everything , but system doesnt see it

Make sure the USB cable is fully inserted into the Mega and your computer.

Try a different USB cable. You might be using a damaged, defective, or charge-only cable.

Try removing all external components/wiring/shields/etc. from your Mega.

Make sure your Mega is not sitting on an conductive objects like a metal tabletop, bare wires, or coins.

Does your board LED blink once after double-tapping the reset button?
