After I changed email to my account (my email had been confirmed). I then login Service Studio App using my new email account, when I click on the "Log in" button, it loads and after that it stopped loading, nothing happened. (I can spam clicking the Logging button many times but the results are still the same thing).

This also happens same thing when I logged in with environment URL. I inputted the environment URL same as in my infrastructure in Trial Portal (like how I used to do as usual) and it still not work. Nothing happened after the Logging in button loaded.

Hope I will get some good responses asap. Thanks!
