Free Fire Guest Account Hacked After Update - Cannot Link Google

I am writing regarding an issue I experienced with my Free Fire guest account on a Xiaomi device after the latest update. As soon as I downloaded the new update, my guest ID appears to have been hacked and I can no longer access or use it normally. This guest account was important to me even though I did not spend any money or buy diamonds on it, because it contained all my game progress and effort. After the update, I noticed that the account was no longer under my control and I believe someone else has accessed it without my permission. My request from you is to help me recover my hacked Free Fire guest account and then assist me in safely linking it to my Google account, so that my game data is protected and this problem does not happen again in the future. I kindly ask you to check my account situation and provide a solution to restore my access and secure it with Google linking. I am contacting you about this problem for the first time and I kindly request a quick and clear response about what can be done to recover this hacked guest account and connect it to Google in a secure way.
