Remove Hacker From Instagram Account

@iamsumiayya_ this is my id...I’m still logged in to my Instagram on one device, but every ownership detail—email, phone number, even backup codes—has been swapped out by the attacker. Your task is to walk me through, or remotely execute where possible, the complete removal of the hacker’s email and phone number so they lose all access. Here’s what I need from you: • Use my current in-app access to replace the attacker’s credentials with my own verified email and mobile number. • Confirm that the change is irreversible for the intruder (revoking any sessions they might reopen). • Reinforce the account with two-factor authentication and fresh recovery methods. • Provide a brief checklist I can follow in the future to keep the account secure. I can supply real-time screenshots, OTP codes, or anything else required during the process. Once you finish, the only contacts listed under Settings → Personal Information should be mine, and I want written confirmation that all active sessions except my devices have been logged out.
