I have the exact same problem. It’s saying something about not being able to confirm my identity? I took a look at the dev tools and it’s apparently making a request to a server which returns an error.

It only works in incognito because it’s using a different ip address there…

Funny, I had this problem yesterday when I tried to login to Apple Business Manager. Thought I had messed up but worked fine in incognito.

Sorry, how is it that you make Chrome incognito window use a differnt IP address?

That sounds like a good magic trick.

Beats me. Same computer, same browser. Don’t know whether it’s the exact same address though. Cleared cookies already. Still only working in incognito.

Exact same problem, exact same error. Glad to know I'm not alone!!!
