Pop up windows blank

Hi I hope you can help.

We’ve been experiencing Rhino 7 with black viewports on application start up - changing from wireframe to shaded and back refreshes the viewports.
I’ve Uninstalled and reinstalled Rhino only to realise that the pop up windows are also blank - for example when entering the license information for Rhino on first start.
Tried installing Rhino 6 and have the same issue
Also consistent across user accounts.
Tools > Options > Plugins
Tools > Options > Rhino Advanced
both not displaying

Safe mode launches as expected but Tools menus not available either

Quite new to troubleshooting Rhino so any help appreciated
ran SystemInfo command

grab a new driver for your graphics card.

when you install it, use the custom option, then check the “clean install” box-

restart and try again. If that does not fix it, please let us know.
