No bitcointalk doesn't have any official email to avoid agents impersonating officials of the forum.
There is no official email for contacts in general, but forum has many emails (official) and those emails end with @bitcointalk.org
If that doesn't work, email recoveries_2021_xxlgg@bitcointalk.org, ideally from the account's email address. Include your username. A signature will likely be required (see below).
If you have a locked account, send a new email to the @bitcointalk.org email address given in your "account locked" error message. (The email address changed a few weeks ago.)
Email addresses for contact support of locked, hacked accounts can be changed time to time by forum admins. It's not correct to say Bitcointalk.org does not have its official emails.
