Hey Scott, thanks a lot for letting us know,
It will be great if you can offer more detail about your WP setup [so we can try to replicate the issue] or provide access to your environment, the freeze has not been spotted in our tests nor reported by others.
Regardless, you can X out the wizard at any time and take the slightly harder way to set up your first live stream, see tutorial here https://youtu.be/TopBhvGvwbs
Best wishes, Christina
