Stuck at *** ReportProcessor.ProcessReport STARTED ***

[Abhijit]

Telerik Reporting R3 2022 SP1 running with a ASP.Net MVC project(.Net 4.8), in Visual Studio 2022.

I was able to generate reports smoothly till yesterday. I could make changes in the Visual Studio designer and restart my MVC project and see changes quickly. From today I am seeing the report generation gets stuck at :

*** ReportProcessor.ProcessReport STARTED ***

This is the line:

RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

If I restart the system, and run my MVC project then it generates reports. However if I stop the project and re-run it, it gets stuck at the above line. And no matter what I do this error does not go away. 

I have reinstalled Telerik Reporting but no success.

How can I find out where its getting stuck? Can I make the Telerik Reporting print some useful debugging lines in the Output tab?

This project has been working for over a year now in many systems, so its really surprising.

Here is the top of the stack after control goes into Telerik:

Hi, Abhijit

A possible cause for this issue is that some of the references used are outdated, can you try updating them using upgrade wizard, to make sure that everything is up to date?

If that does not resolve the issue, can you provide the following logs so we can diagnose the error? 

• Fiddler Jam log - This will log information about client-side issues if there are any: How to Record a Log with the Fiddler Jam Extension- YouTube
• Trace log - This will log the errors thrown on the server, where the reports are resolved: How to: Create and Initialize Trace Listeners - .NET Framework | Microsoft Docs. For an ASP.NET Core project, see How to troubleshoot errors in ASP.NET Core projects - Telerik Reporting instead.

Does this issue occurs when you are trying to render a specific report or is it reproducing for different reports? If it is for a specific report, would you provide us with the report definition, if it occurs for multiple reports, can you send the MVC project so we can inspect it further?

I will be looking forward to your response.
