ModuleNotFoundError: 'mmap' is present in the Mitogen importer blacklist

Ansible 2.15.8
Ansible is not patched
No custom modules
Did not tried latest master version from Git?
Debian 12 (Bookworm)
Host Python 3.9.2, target Python 3.11.2

this task:

- name: wait for port 53 to be open on localhost
  wait_for:
    host: localhost
    port: 53
    state: started
    timeout: 120

leads to this error:

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ModuleNotFoundError: 'mmap' is present in the Mitogen importer blacklist, therefore this context will not attempt to request it from the master, as the request will always be refused.

Sorry for the wait. I wasn't able to to reproduce this error, with the following

- hosts: localhost
  vars:
    ansible_python_interpreter: /usr/bin/python3.11
  tasks:
    - wait_for:
        host: localhost
        port: 22
        state: started
        timeout: 5
