Ansible WinRM: Unknown failure when polling update result - attempting to cancel task: pop from empty list

Question

Linux Ubuntu 18
Ansile 2.9.27
Python 3.6
pywinrm 0.4.2
Remote host: Microsoft Windows 10 Enterprise

How to fix the error pop from empty list ?

Ansible playbook code:

   - win_updates:
       category_names:
         - CriticalUpdates
       reboot: no
       reboot_timeout: 1000

Ansible console log showing Warning:

<1.2.3.4> Running win_updates - round 1

Potential workaround The code fails in win_updates.py --> offset = int(lines.pop(-1)) , when lines is empty. Is lines = stdout.splitlines() expected to return something always? Otherwise, we can just ignore the pop(-1) when it's empty.
