Google Account Hacked – Recover Gmail Linked to Free Fire

I am writing about a serious issue with my Google account which is linked to my Free Fire game and which I also need for my personal use. Around a year ago, while I was playing Free Fire, I was suddenly logged out. When I tried to log in again with my Google account, I saw that my password had been changed even though I was not the one who changed it. Since then I have not been able to access this Google account at all, so I stopped trying for a while and quit Free Fire. Now I need this account again both to recover my Free Fire progress and to use it for my personal needs, but I still cannot log in. The account was originally created and used on my previous device, a Samsung Galaxy Tab A. I am attaching a screenshot of the Google security email stating that my password was changed, which I did not authorize. I could not recover the account on my own and I have not received any support about this issue yet because I did not know how to proceed. I kindly request that you investigate this unauthorized password change, verify that I am the legitimate owner using the available information and device history, and help me regain full access to my Google account so that I can also restore my Free Fire game progress.
