Welcome to Microsoft Q&A!
In this case, the Crystal Reports version for Visual Studio 2005 is no longer maintained by Microsoft as it has been deprecated along with other older technologies like Adobe Flash. While there are still some security updates available for Visual Studio 2005, the product itself is missing many updates and support for current operating systems and security updates.
In case you need the source information: https://community.sap.com/t5/technology-q-a/sap-crystal-reports-end-of-life/qaq-p/12516182
I hope the information was useful.
Best regards,
