Correct way to read AWX custom credentials variables in an ansible playbook

Im trying to pass user credentials from an AWX custom Credential Type that I named Ansible Vault to my ansible playbook. The credential is read fine in my Test Playbook, but when trying to use the credential to connect to the managed server it fails with error: fatal: UNREACHABLE! => {"changed": false, "msg": "ntlm: the specified credentials were rejected by the server", "unreachable": true}

In the Ansible Vault credential I have this

Input config:

fields:
  - id: ansible_become_password
    type: string
    label: password
    secret: true
required:
  - ansible_become_password

Injector config:

extra_vars:
  ansible_become_password: 'myfakepassword'

My Test Playbook

---
- hosts: myhost.com
  
  vars:
    ansible_winrm_password: "myfakepassword"
    ansible_user: ansiblerunner
    ansible_connection: winrm
    ansible_port: 5986
    ansible_winrm_transport: ntlm
    ansible_winrm_server_cert_validation: ignore
    source_file: "../files/test.txt" 

  tasks:
    - name: Print Username from Credential
      debug:
        var: ansible_become_password

My non working playbook
