Unable to Authorize Steinberg Activation Manager

I have been trying for days to active my Cubase 12 with no success

When I try to Sign in from the Steinberg Authorization Manager I get this message:

Authorize Steinberg Activation Manager

To authorize Steinberg Activation Manager, you must allow your browser to open Steinberg Activation Manager. Once authorization is completed, you can close this page and continue working with Steinberg Activation Manager.

Try Again

and it never works. I have tried Edge and Chrome with no success. I have allowed both browsers to open Steinberg Activation Manager

Any suggestions?
