This article explains the manual changes required when upgrading to Telerik Reporting R1 2018 SP3 (188.8.131.526).
REST Report Service Implementation
In all the REST Report Service implementations (WebAPI, Service Stack, ASP.NET Core), the HttpContext.Current instance is not accessible in the rendering thread. Instead the rendering thread makes use of the new property UserIdentityCurrent, which is also available in the report expression context as a global object: =UserIdentity. All the reports that rely on HttpContext.Current, must replace its usage with the new dedicated property.

The viewer is build with Telerik UI Controls for WPF 2018.1.220.40. If you are using a newer version consider adding binding redirects. For more information see: How to Add report viewer to a WPF .NET Framework project
