I can not deactivate my own workflows in CRM 2013 on-premise. I've tried restarting Async Services and IISRESET, there are no suspended system job, no plug-ins imported, only the default solution.
This error appeared only today. Till now everything was OK. The error appeared after activating several workflows for one entity. Could be this the reason?
The error message is:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: System.Web.HttpUnhandledException: Microsoft Dynamics CRM has experienced an error.

Any ideas?
