Razer Blackshark v2 hyperspeed dongle not working.

I’ve bought my headset in december 2024. For two months everything was working great when suddenly wireless dongle wasn’t connecting anymore. Windows does not recognise the dongle, I tried many things, different ports, reinstalling synapse. I tried using pairing utility and firmware updater but i couldn’t do anything because in order for the pairing utility to work i need to connect my dongle and it is not recognized. I don’t really know what to do. Does anybody have the same problem? It’s really frustrating that i have to use the headset via usb cable.
