Essentials Version Update Error: Could Not Create Transform

I've attempting to update a version of essentials from 4.12 to 4.13.1 (also tried 4.13). I've done updates a million times before so its nothing new. When I select the instance to update I get an error stating that "Could not Create Transform", and I cant go any further.  There is nothing custom or special about this instance of geocortex. It uses ArcGIS portal as its user store but that's about the only thing that is changed from default. According to the Role Status diagnostic tool this instance is healthy. 

 

 

I've tried rebooting the machine and geocortex itself, but that (as expected didn't help). I'm not really sure if there are some logs I can look at to see where the error is coming from, or what the next steps are.
