Need Help : UiPath.Core.Activities : Method 'Newtonsoft.Json.Linq.JToken get_Item(System.String)' declared on type 'Newtonsoft.Json.Linq.JObject' cannot be called with instance of type 'Newtonsoft.Json.Linq.JObject'

Other than %localappdata%\Temp, try to see if you have the 10.0.3 version of Newtonsoft in other places, like:

  • C:\Program Files (x86)\UiPath\Studio\Packages
  • %localappdata%\UiPath\Activities
  • %localappdata%\NuGet\Cache
  • Folders of other custom activities that you downloaded or created
