Garena Account Code Issue

I am having a serious problem with my Free Fire / Garena account linked to my Gmail address “pallavro****@gmail.com”. Until around 7 August, I could normally receive Garena verification codes to this Gmail, but between 7–11 August the codes suddenly stopped reaching my inbox and spam folder, even though I did not change my email myself. Right now I cannot log in to the Garena / Free Fire platform because the verification code never arrives to my Gmail, so I am locked out of my account. I am using a Xiaomi phone and this Gmail is the only email that is bound to my Free Fire account, so I have no other way to enter. My request from Garena is that you fix the verification code sending problem to my Gmail so that I can once again receive the codes and log in to my Free Fire account safely. I want to keep using this Gmail for my account; I only need the codes to be delivered correctly again.
