Custom Workflow assembly issue in D365 version 9.0.2.180

 Hi,

Today we faced strange issue with the Custom Workflow assembly in D365 version 9.0.2.180 but it works fine with lower versions of D365. 

• Assembly Build Version: 4.5.2 Framework
• Microsoft.Xrm.Sdk.Workflow.dll version: 8.2.0.749 

Whenever the workflow triggers and hit the workflow assembly step the below error pop-out so could you help us to resolve below issue: 

This happens with Synchronous as well as  Asynchronous workflow. 

Below are the error log details:
