I do see that you have a verified account created back in 2023. If you aren't receiving the email the easiest course of action is to just clear out that web account and let you create a new one with fresh credentials. This won't have any impact on your stats or progress, once you create an account again and connect it back to your meta account everything will be as it was.
If that sounds good I can go ahead and clear the account then you can go to the website & signup again.
