I manage to recover an old main email and there was a Google acc tied to it that I haven logged in over ten years, but despite I having access to the email, I can’t access the Google acc because:

"You’re trying to sign in on a device Google doesn’t recognize, and we don’t have enough information to verify that it’s you. For your protection, you can’t sign in here right now.

Try again from a device or location where you’ve signed in before."

Then don’t give any recovery option :S

edit: Best I could get from their bot is “If you still see the message about an unrecognized device, you can try the recovery process again in a week from the device you are currently using, as sometimes waiting can help Google recognize the new sign-in pattern.”
They won’t just a send a code to the email the acc is tied to, or even to the recovery email the acc is tied to… anyway, gonna try the “sometimes” in a week.
