Errors were found when compiling the workflow. The workflow files were saved but cannot be run.

Question

Greetings All,
I am having issues with a SharePoint Designer workflow.  This is a SharePoint 2013 environment, I'm using SharePoint Designer 2013 and working on a SharePoint 2010 workflow.  I'm developing this as a SharePoint 2010 workflow because I need to do
impersonation.
The environment and workflow have been running, in the past week, without issue.  I went to add a couple steps and now I cannot publish the workflow.  While in SharePoint Designer, I receive the error:
"Errors were found when compiling the workflow.  The workflow files were saved but cannot be run."  When I click the Advanced button on the error dialog, the message is "Unexpected error on server associating the workflow." 
That is all the error information I have available; nothing is in the log files.
I have investigated this error and tried the following:
Cleared the SharePoint Designer cache.
The WebApp.UserDefinedWorkflowMaximumComplexity was at 7000 so I increased it to 10000.  Restarted the servers (which may not have been necessary) and tried again receiving the same error.  I then increased it to 30000 with the same error result.
Since this is a large workflow, I tried created a workflow with a single action, write to workflow log, with the same error results.
I reboot the servers and try again and now I can publish the small test workflow but not the original.  However, neither will run.  When I attempt to manually run the small test workflow on an item, I get an error: "Sorry something went wrong.
An unexpected error occurs.  I checked the log files for the correlation id and nothing, nothing was logged for the error. ~arg~
Also, now no workflows can be published in this web app.  Not just the one I was working on but none of them!
Does anyone have a clue what has happened to the SharePoint 2010 workflow service?  Or some suggestions for me to try?
Thank you in advance for your help!

Hi Sagar,
I appreciate it but if you see my original post, this is a SharePoint 2010 workflow that cannot be published; which has now caused all SharePoint 2010 workflows in the same web app to error.
Your first link is specific to SharePoint 2013 workflows.
Your second link refers to the UserDefinedWorkflowMaximumComplexity.  If you read my original post, I've already tried this and I've tried to publish a small (single activity) workflow.
Your third link also refers to large workflows with many approval activities.  My workflow doesn't contain any approval activities.
And you fourth link refers to 2013 workflows not 2010.
My issue is with publishing and running a SharePoint 2010 workflow in SharePoint 2013.
Thank you...
