Ansible Playbook skip some play on multiple play playbook file

I have an ansible playbook YAML file which contains 3 plays.

The first play and the third play run on localhost but the second play runs on remote machine as you can see an example below:

- name: Play1
  hosts: localhost
  connection: local
  gather_facts: false
  tasks:
    - ... task here

- name: Play2
  hosts: remote_host
  tasks:
    - ... task here

- name: Play3
  hosts: localhost
  connection: local
  gather_facts: false
  tasks:
    - ... task here

I found that, on the first run, Ansible Playbook executes Play1 and Play3 and skips Play2. Then, I try to run again, it executes all of them correctly.

What is wrong here?

The problem is that, at Play2, I use ec2 inventor like tag_Name_my_machine but this instance was not created yet, because it would be created at Play1's task.

Once Play1 finished, it will run Play2 but no host found so it silently skip this play.

The solution is to create dynamic inventor and manually register at Play1's tasks:

Playbook may look like this:

- name: Play1
  hosts: localhost
  connection: local
  gather_facts: false
  tasks:
    - name: Launch new ec2 instance
      register: ec2
      ec2: ...
    - name: create dynamic group
      add_host:
        name: "{{ ec2.instances[0].private_ip }}"
        group: host_dynamic_lastec2_created

- name: Play2
  user: ...
  hosts: host_dynamic_lastec2_created
  become: yes
  become_method: sudo
  become_user: root
  tasks:
    - name: do something
      shell: ...

- name: Play3
  hosts: localhost
  connection: local
  gather_facts: false
  tasks:
    - ... task here
