Free Fire Gmail Unbinding Risk - I Cannot Receive Garena OTP Emails

I am reaching out for immediate assistance in recovering my Free Fire account. I accidentally unsubscribed from OTP emails from Garena in my Gmail, and now I'm unable to receive verification codes. Regrettably, I shared my account ID with a friend, and now he is attempting to unlink my Gmail from the account without my consent. There are just 9 days remaining until my Gmail will be permanently disconnected from the account. I feel quite anxious and am determined to take all the essential measures to protect and recover my account before it becomes too late. My Player ID is 1895482377.
