the problem with entering the icloud. Heelp

I broke the iphone 6, recently, and there was mail on it to which the icloud is tied, when entering the same icloud on my new iphone X, he writes that "Your account is blocked for security reasons. Select the unlock method", when trying to unlock, I enter the apple ID, confirm all the cases, after everything I have done, a letter should come to the mail in order to confirm whether I am it, but the problem is that the letter comes to the phone that is broken and I can't log in to it in any way, what should I do in such a situation? When you know the password and login, but you can't login because of such a banal problem. Also, when I register my mail on a new iPhone, I also write "Your account is blocked for security reasons. Choose a way to unlock", I'm just confused, for me it's all somehow illogical, tell me what needs to be done.
