Google Account Hacked - Unable To Recover Access

I am writing regarding my Google account with the email address hbariya***@gmail.com, which appears to have been hacked. Since around 1 January, I have lost control of this account and can no longer use it safely. My main request is to recover full access to my Google account and remove any unauthorized access. I have already tried the account recovery process once, but I was not able to regain control of the account. I use this account in India, and it is linked to the recovery phone number 9601446***. I request that my account be reviewed urgently, the hacker’s access be removed, and that I be guided on how I can securely regain access to my Google account as soon as possible.
