PBIRS - Error adding/removing Favorites

I am currently receiving an error any time a user (including site administrators) attempt to favorite or remove a favorite of any report.

Something went wrong.

The RSPortal log is showing the following:

I'm stumped by this error.  I have two other servers that are not experiencing this error running Developer edition of PBIRS while this is running EE SA edition with a valid key.  I've compared services, permissions, properties, etc.  The only difference I see is that the Installation size in Add/Remove is 192MB while the Developer versions are 91.5MB.

My last resort (which I'd like to avoid) is to uninstall/reinstall with a new database and re-publish all of the reports. 

Any thoughts?
