The only option I saw so far was to enter an existing email after multiple iterations of "Try another way" option. That email received a verification code. I put that code in the recovery window and then saw this:
"Reply to your Google support email or contact to let the team know you've successfully completed your account recovery request.
To try signing in again, follow the steps in our Help Center on how to recover your account."
Can you try setting up a new gmail account then use that as part of the recovery assuming it offers as an alternate another gmail account.
