Hi Dominic, I'll upload a fix as soon as the unblock request for ansible-base goes through. As a workaround you can also set the python interpreter as described in [0], either changing the default or setting it for individual hosts.
I'm not sure if putting python3 further up the list might break non-Debian systems (which could be targets where this code runs), I'll have to check that first. FYI, for 2.12+ the interpreter discovery will depend on the target OS detected. You can already test it by setting interpreter_python=auto in the [defaults] section of ansible.cfg.
