TikTok Does Not Recognize My Old Account During Recovery

For about one month I have been trying to recover my old TikTok account, which is linked to my phone number and Gmail address, but TikTok does not recognize the account anymore. When I try to log in or recover it with my Gmail, I receive an “account not recognized” message and I cannot access my profile. I am attaching a screenshot of the profile page to show which account I am talking about. Despite several attempts, I have not been able to restore access through the normal recovery options in the app. I request your support to help me access this old account again and to restore it to my control as soon as possible.
