Razer Nari Essential earbud not working and Firmware update not finding USB Dongle

Hi Razer Team and Community,

sadly my right Razer Essential earbud does not work anymore. I Tried the pairing tool, and it worked, but m right earbud didnt came back to live. so i tried to run the firmware update tool, but this time the tool does not find the USB dongle, tried multiple usb ports, reinstalled the driver, no chance.

Any idea?
