I will post this here as well since I want to help you out: I had this as well and I figured out how to fix it since I do these kind of things for living. It's probably a bug, they have probably released a new version of the site and your browser has cached som old invalid data. To get rid of it easily by using Chrome: Right click and open "inspect". Press the tab "Application". On the right side under "Local storage", right click the URL http://disneyplus.com and select "Clear". Refresh the page and you should be all set. When you clear the data as shown above you will not clear any other saved data for other websites. Only the data connected to disney plus! When you refresh you will get all the new data again.

Have you tried using disneyplus.com/start? I was having the same issue for weeks, disneyplus.com/begin never worked for me - I tried on multiple devices, in incognito mode, etc. Nothing. A few minutes ago Disney support suggested I try disneyplus.com/start instead and it finally worked for me. I was using my laptop in incognito mode, in case that makes a different, although I also tried that with the /begin URL and it still didn't work so I don't know how much that actually matters.
