itch.io

I solve this by emailing itch email support and they correct a typo in my email address.  

My email provider is proton.me, do you think they reject emails from you?

It's mentioned in the documentation here: https://itch.io/docs/advanced/two-factor-authentication

Itch.io uses email two-factor authentication, proof: https://imgur.com/a/RA3JawT

My account Light Games has an email on proton.me and when I log in, it needs two-factor authentication. But my email doesn't show in my mailbox in proton. (My email is in the account correctly, I checked it before I logged out from the account and I contacted email itch support) I need help please.
