Why are you blindly upgrading? The only safe way to use Ansible in production or on a team is to pin the version everyone uses because even minor releases can break playbooks and change behavior.

I'm not sure of the details, but it has something to do with the modern way of CI/CD pulling in random 3rd party docker containers.

Sounds like your docker was pulling latest instead of a versioned tag. I'd update that and be happy this only cost you a few hours.
