Upgrading 6.5.12 - messed up the system

We installed 6.5.12 cumulative from here:

https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html

Now, I open a workflow model and click "Add variable" and it does nothing.  I opened the javascript console and I receive the error below.

This is a big problem.  

Did I miss another update?  What's the deal?
