SharePoint 2013

Client Installed July SharePoint CU and nothing related to Nintex worked.  They then uninstalled the CU and workflows could then be published and started.  

But ever since, scheduled workflows are producing Failed on Start error.  I added the int64 entries into the config files, but that didn't resolve the issue.  I tried re-publishing the workflow, recreating the schedule, uninstall and re-install the Schedule Workflow timer job, but the issue persists.

I'm out of ideas so hoping someone can assist.  I'll provide more information if needed.

Here is the ULS entries when it tries to start via scheduler:
