Deathadder V2 X Hyperspeed dongle problem

The mouse was working perfectly on the 2.4GHz dongle, but then it started not being able to connect with the dongle. Now it has stopped working on 2.4GHz altogether.

Bluetooth still works fine, and Razer Synapse detects the mouse properly when connected via Bluetooth. However, when I switch the mouse to 2.4GHz mode, Synapse shows the device as turned off.

I have already updated the dongle to the latest firmware, and used the pairing utility but it does not seem to do anything. It doesn’t complete the pairing or restore the 2.4GHz connection.

I also tested the mouse and dongle on another laptop, and the issue is exactly the same, so it does not seem to be related to my computer or Synapse installation.

Could you please advise on the next steps? Is there a way to reset or re-pair the mouse and dongle properly, or could this be a dongle or hardware issue?

Thanks.
