The character creating thing loads with the server, i guess you could put it that way. If you fail to connect to the server at some point during creation your most likely gonna have that "freezing" problem your having. I dont think it will stop on its own, you can wait and find out if you want but who knows how long that will take.
I dont believe there is a way to fix this, but i tend to re-connect my internet. It sometimes works otherwise i have to keep pressing the Log In button on the start menu.
