Solution

It appears that the user is hitting an error that is being thrown by your login-after-email-verify Action when a user's email address is not verified. Errors thrown in Actions will be returned to your application's callback endpoint for your application to handle however you see fit. From the looks of the video, your application is immediately redirecting back to a login route instead of handling or displaying the error. This is causing a loop.

As a quick fix, disable the Action or remove it from the post-login flow. Then confirm that your application is prepared to appropriately handle errors returned to the callback endpoint instead of redirecting immediately to login.
