Email Validator only accepts 2-3 letter TLDs.

The email validator regex only accepts 2 and 3 character top-level-domains. The current longest TLD is .vermögensberatung (XN--VERMGENSBERATUNG-PWB), which is 24 characters long. The longest possible is 63 characters long. I personally use a .scot email address, which gets rejected by email fields.
