@Olegt0rr thanks for reporting

This appears to be a mitogen issue itself. See here for a bug report on their repository: https://github.com/mitogen-hq/mitogen/issues/652.

The mentioned issue has been closed with a fix for Ansible 2.10+ here: https://github.com/mitogen-hq/mitogen/pull/715

So I guess there is nothing I can do on my project as it is mitogen related.
