Facebook Locked My Account After I Changed My Email and I Lost My FF ID

My Facebook account has been locked. I changed the email address and phone number linked to my Facebook account, and suddenly, it got locked. I did not receive any prior warning or notification about this change causing an issue. I request a review of my account, as it was disabled for no reason. Why was it closed? I entered the verification code, but it still didn’t unlock. My Free Fire account, which was linked to Facebook and is worth ₺30,000, is now gone. I have spent years building my profile and making in-game purchases, and now I can’t access any of it. I request an immediate review and reinstatement of my account. Thank you in advance.
