"Unable to load plug-in assembly" error Dynamics 365 On-Premise when debug workflow activity

Hi Guys,

I am getting an error when trying to profile a workflow. My custom workflow is using the .NET Framework 4.6.2.

I created the workflow in CRM and added the step. In the plugin registration tool, I try and profile the workflow and get this error:

   Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Unable to load plug-in assembly.

Any ideas?
