Cannot Receive Gmail Verification Code

I am writing regarding a problem with logging into my Free Fire account due to an issue with the email verification system. My account is bound to a Gmail address, but for the past few days I have been unable to receive the verification code that is required to log in. Although I do not remember the exact date when this started, it has been happening for several days in a row. I carefully checked my Gmail inbox, including the Spam folder and all other tabs such as Promotions and Updates, but there is no verification email from Garena or Free Fire. I also tried resending the verification code multiple times and waited between attempts, yet no code was delivered at any time. I previously contacted Garena support about this problem, but unfortunately I did not receive a proper solution and the issue is still ongoing. Because of this, I am currently unable to access my Free Fire account. I kindly request your help to fix the email verification issue so that the verification code can be successfully sent to my Gmail account and I can log back into my Free Fire account securely.
