Ansible is using the Python interpreter /usr/bin/python3 on the remote, which apparently does not satisfy the version requirements. SyntaxError: future feature annotations is not defined indicates that /usr/bin/python3 is older than Python 3.8, the minimum requirement for ansible-core 2.18 (https://docs.ansible.com/ansible-core/devel/reference_appendices/release_and_maintenance.html#ansible-core-support-matrix). From the error message I’d guess it’s Python 3.6.

You have to point Ansible at a newer Python version on the remote to be able to use it.
