SP 2013 Running Workflow giving Error - Sorry Something went wrong

Question

Hi,
We have publish workflow running on a document and we need to cancel/ terminate it.
On the workflow Page we can see under the "Running Workflows" , the workflow is running. But when we click on that it gives the Something went wrong error message. As we are not able to goto the workflow status page on UI, we dont get option to
End the workflow. 
To Cancel the workflow we tried following things -
1. Powershell command to get the workflow object and cancel it. But using the powershell command- $listItems.Workflows does not give the instance of this stuck workflow. If we start new workflow on that item , it will get added to the count but this stuck
workflow does not come under its count. So we are not able to get its instance using powershell and cancel it.
2. Using client side programming we tried directly passing the workflow instance name and terminate it but it gives the exception that "given key was not present in the dictionary"
string workflowGuid = "91ee281b-3938-45a5-9bb2-8bd128bfa90c";
var workflowServicesManager = new WorkflowServicesManager(clientContext, clientContext.Web);
var workflowInstanceService = workflowServicesManager.GetWorkflowInstanceService();
WorkflowInstance instance = workflowInstanceService.GetInstance(new Guid(workflowGuid));
workflowInstanceService.SuspendWorkflow(instance);
Please let us know how to get rid of this stuck workflows.

Hi Prashant,
According to your description, my understanding is that you want to cancel the stuck workflows in SharePoint 2013.
If the workflow is designed in SharePoint, I recommend to go to the Workflow Settings of the document library, click Remove, Block, or Restore a Workflow to remove the workflow with the stuck instances and then republish the workflow from Designer to SharePoint.
Or you can use the code in the link below to cancel all the workflow instances to see if the issue still occurs:
