Problem with login access and security on iOS 26, iPhone 13 Pro Max

Hi, I have an iPhone 13 Pro Max running iOS 26.0 (beta).

After installing the update, I get a message stating that I need to update my Apple account settings. When I log in, it freezes and nothing can be done.

I also can't access the login and security settings, as it also freezes and won't progress.

Also, the option to install beta versions has disappeared. I don't know why? Could it be that since I have the latest beta, the option disappears until a new update?

Please help!
