Why am I receiving the error "RuntimeError: Failed to start work unit: unknown work type local" after I upgraded the RHEL in Ansible Automation Platform 2?

• When I upgrade the RHEL, all jobs fail with the error message “RuntimeError: Failed to start work unit: unknown work type local” in Ansible Automation Platform.
