Actually, here's another workaround you could try.
While on the screen where you have to press "Yes", do this:
Press the V key, which enables the self-voicing feature
Press the "Right arrow" key. See if the "Yes" option becomes highlighted.
If it is highlighted, press Enter to confirm.
After that you can deactivate self-voicing by pressing V again.
Tell me if it works. Hopefully it does. We'll keep trying to figure this out on our end.
