Hacked Gmail Account and Unauthorized Password Change

I am writing because my Gmail account with the address “khanbibi***@gmail.com” appears to have been hacked and my password has been changed without my permission. I can no longer access my account. When I try to log in, the system asks me to finish signing in again, but I cannot complete the process because the hacker is not sharing any login or verification code with me. For this reason I am completely locked out of my Gmail and all the information and accounts connected to it. I request that my Gmail account be recovered and that access be returned to me as the rightful owner. I also ask that any suspicious activity carried out after the hacking be investigated and that my account be secured so that such an incident does not happen again.
