This issue was really a headache for me today. In my farm of four servers i have 2 WFE and 2 APP servers (of course a DB server separately). I have configured Workflow Manager on 1 APP server and Workflow Manager Client on all of the remaining servers. Suddenly i started getting error on workflows and the GUID lead me to the below ULS logs of SharePoint.

I would really like to thank Stephan Bren for answering here and it worked for me perfectly fine. Below are the steps i followed and it worked. You may need to do further steps in case the issue do not fix.
- Install hotfix KB2880963.
- On the application server hosting Workflow Manager 2013, stop and restart these services:
- Service Bus GatewayService
- Bus Message Broker
- Workflow Manager Backend
- Lastly, restart IIS on the WFEs.

- Workflow not working after installing Service Pack 1for SharePoint 2013
- The Magic of Get-SPProduct -Local
- Deploy software updates for SharePoint 2013
- Install a software update (SharePoint 2013)
- After installing this hotfix on all of the SharePoint 2013 servers, you may find that running the SharePoint Products Configuration Wizard returns an error:
Error: Some farm products and patches were not detected on this or other servers. If products or patches are missing locally...
If this occurs, execute Get-SPProduct -Local on each of the machines identified in the error message. It may take several minutes for this command to finish. - In Solution Step 2), above, I mention restarting workflow services. It's not clear to me whether all of them need to be restarted, one or more of them, or maybe just restarting IIS, or some other combination of these. Whichever the case may be, this is the combination I did to recover from experiencing an error clicking on Workflows for a list item, after installing the hotfix. This approach worked for resolving this problem on both my development and production farms.
