Hi @Shardul Pasare ,

• Firstly, please clear the SharePoint Designer cache via the following steps:
  Close SharePoint Designer if it is open -> Using Windows explorer, go to: %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache, delete everything inside that folder -> Now go to: %APPDATA%\Microsoft\Web Server Extensions\Cache, delete the contents of that folder as well.
• As this is a migrated workflow, You may need to ensure you are adding the authorized type node to the correct place since its changed in 2013 to the targetFx node.
  Please take a reference to this article: SharePoint 2013 Custom Workflow Actions Don’t Run Properly (Could not deserialize object)
