I had an ancient Google account that I hadn't logged into in forever that put me into a similar recovery loop. I had the correct password for the account and it said I was logging in from a new device and asked for my recovery email. It sent a code to my recovery email account and I entered the code into the page. So Google knew the following: 1) I have the correct password to the Google account 2) The recovery email address is valid and the code I entered matched Despite that, after entering the code I received an error message stating essentially "Thank you for providing the correct code however we are still unable to verify your account". I then reached out to a contact within Google and they escalated the issue and the account access was restored for about a week or so before it went back into the same recovery loop. I gave up after that.
