Is there a serial device (COM port) listed on your OS?
If yes click on the serial button on mu editor and press Ctrl+C. What does it show?

Two possiblities

1) Driver is not properly installed

2) Faulty serial port on your hardware

Serial port is working as it is opening circuit python drive. Can you share me link of the driver that will help me see COM port on device manager.

Not necessarily as the console and drive are different USB device types.

Are you trying to access REPL using nRF USB connector or interface USB connector?
Try with interface USB connector ( the JLink USB ).
I haven't read the circuit python implementation code. But it looks to me that nRF5340 USB is only acting as MSD.
