Unable to log in to ubuntu instance. ssh keys still require a password

I lost access to the ssh key granted when initially creating my always free VM.Standard.A1.Flex running ubuntu 22.04 so I followed the guide from here https://docs.oracle.com/en-us/iaas/Content/Compute/Tasks/connect-to-linux-instance.htm#top. I downloaded a key for a console connection and tried to connect locally with ssh from a laptop running ubuntu 22.04. When running the ssh command

ssh -i ./ssh-key-2023-11-23.key -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa -o ProxyCommand='ssh -i ./ssh-key-2023-11-23.key -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa -W %h:%p -p 443 <provided url>' <provided url> -vvvv
