Unable to Access My Gmail Account

I have been unable to access my Gmail account (address: jadavalp***[email protected]) for about two years. When I try to sign in, I receive a “Couldn’t sign you in” error and I am asked to confirm a code that is sent for verification, but I cannot complete this step. Because of this problem, I have completely lost access to my Gmail account and the services connected to it. I shared screenshots of the error and the verification screen that appears during the login process. My request from Google is to help me recover and reopen this Gmail account and to provide a way to verify my identity and restore access without sending a verification code to the inaccessible Gmail. I specifically request that the verification code be sent to my other Gmail address so that I can complete the process and regain control of my original email.
