@Studd3rboxxx What phone are you using? If Android, make sure to upgrade to the latest version. Also check your Google Play services to make sure it's on the latest update. I've seen some people managed to get it working this way.
Otherwise, if you have another phone you can use, you can try that to make sure the issue is not with your phone.
I am having this same issue, I have a one plus 7 pro. I can't get past that screen, I think it's trying to get to a payment setup screen, but never get's there. I've updated my phone as much as possible, I rebooted it, I uninstalled and re-installed the stadia app. Nothing. Just a spinning icon.
