Unable to Log In FF Through Facebook

I am writing regarding my Free Fire/Garena account, which I use with the nickname visible in the attached screenshot. I have not been able to access this account for about 10 days. Previously I always logged into this Free Fire account through my Facebook account. Now Facebook does not log in at all and I cannot open my Free Fire ID. Because of this problem, I have completely lost access to my game progress and profile. I kindly request your help to recover this Free Fire account and restore my access. I want you to help me by resetting or changing the Facebook login/password linked to this Free Fire ID so that I can safely log in again and continue using my account. I am ready to provide any information you may need to verify that this ID belongs to me. I request that my issue be checked as soon as possible and that my Free Fire account access be restored.
