ovn-kubernetes: Playbook hangs on OVS Docker network setup | Run setup_ovs_docker script

The playbook currently hangs in the step OVS Docker network setup | Run setup_ovs_docker script. This step should have a timeout of 120 seconds but it has been running for about half an hour now and has not completed yet.

On my Windows node I see that the script is still running, though it does not seem to do anything. The log file at C:\Program Files\Cloudbase Solutions\Open vSwitch\logs\ovs-vswitchd.log just keeps repeating the following logout put several times per second:

I am using a Windows Server 1803 instance on AWS for the setup.
