Created Unassigned: Script keeps halting, can't figure out why [22050]

I am running this on a SharePoint 2013 farm install, one SharePoint server, and one sql server. The script keeps halting on this error as shown below. I cannot seem to figure out why. This is about the fifth time I have ran it, it did make it through the software install, and this server is "offline" from the internet due to location... Any help is greatly appreciated.
