Razer synaps 3 mouse tab not opening

Hello, when I try to open the mouse tab on razer synaps 3 it does not open.

When I click on mouse it brings up a little grey bar at the bottom showing my mouse ( razer deathadder v2)

Clicking the grey name does nothing.

The software is updated and I have switched USB Ports.

I have also registered the mouse.

I can still change the DPI with the buttons on the mouse.

I just want to be able to turn off the chroma lights.

Yes I have uninstalled and reinstalled.

Thanks
