The linked question "How do I recover my Google (or Gmail) account, password, or username?" is the canonical post for Google account recovery questions. The post is updated from time to time as information changes and I will be making some additional updates as a result of our discussion to make it more broadly reflect changes to the way these types of questions are typically framed versus when the original need for the canonical answer was identified.
Unfortunately, this site's model and standards don't provide a way to do troubleshooting using posts or comments.
I have however moved the question's comments to a dedicated chat where I am willing to engage with you in more detail to better identify and perhaps even resolve your issue. Other community members also have access to the same chat and can weigh in to assist you.
