Recover My Gmail Please

I am having a serious problem accessing both my Gmail account and my Free Fire game account, and I need help from your side to recover my Gmail. About two weeks ago, my Gmail account (eolanrewaju***@gmail.com) was logged out and since then I have not been able to sign in again. Every time I try to log in or recover the account, I get a message saying “Couldn’t sign you in” and that a verification code has been sent to this same Gmail address. Since I am logged out of the email, I cannot receive any code at all. I have already tried the normal recovery options, including “Forgot password” and “Try another way” but there is no other useful option shown for me. It always ends with asking me for a code sent to the Gmail that I cannot open anymore, so I am stuck in a loop with no way to verify my identity. Because this Gmail is also linked to my Free Fire account, I have completely lost access to my Free Fire game as well. I live in Nigeria, and this situation is causing me a lot of stress because I cannot use my email or my game account. I kindly request that you help me recover this Gmail account by adding a recovery phone number for me or providing another secure way to verify my identity that does not depend on sending a code to the same locked Gmail address. I am ready to provide any necessary information to prove that I am the rightful owner of this account and would appreciate your urgent assistance.
