Win updates not rejected

Hello,

i am new to ansible and trying to learn. At the moment i want to install windows updates. That works. But now, i want to exclude a specific update.
As the documentation ansible.windows.win_updates module – Download and install Windows updates — Ansible Community Documentation says i can use reject_list: for that.
But the update is not rejected.
My playbook yaml file:

- hosts: windowstest
  tasks:
    - name: Windows Update
      win_updates:
        category_names:
          - Security Updates
        state: installed
        log_path: c:\ansible_wu.txt
        reboot: true
        reject_list:
          - '.*KB5034439.*'

I also tried

- hosts: windowstest
  tasks:
    - name: Windows Update
      win_updates:
        category_names:
          - Security Updates
        state: installed
        log_path: c:\ansible_wu.txt
        reboot: true
        reject_list:
          - KB5034439

And also the host needs a reboot, but ansible dont trigger that reboot.

What goes wrong?

it was as issue with an older version of ansible. I used the ansible version in the ubuntu 22.04 lts repository. After updating to 2.16.4 the rejecting works well.
