STM32L476 NUCLEO -64 board stopped responding?

[AJosh.6]

I am using STM32L476 NUCLEO -64 for the testing few trial code but the board suddenly stopped to respond, giving me errors as follows :-

14:45:30 : ST-LINK error (DEV_CONNECT_ERR).

14:45:35 : ST-LINK error (DEV_USB_COMM_ERR).

14:45:35 : Error: Problem occured while trying to connect.

USB communication of the board has stopped thus I am not able to test or program my code on the board. Please Help Regarding The Same.

Hello,

Tried to do that too, but even that gives me connection error. Multiple USB Cables also have been checked with the board, for verification.
