Hi @Patil, Mangesh,
Welcome to Microsoft Q&A!
Have you tried to clean and rebuild the solution?
You can backup the project and try to reinstall the package GrapeCity.ActiveReports by right-clicking on project > Manage NuGet Packages.
If the project works normally in VS2022 version 17.8.4 and you can’t update GrapeCity.ActiveReports to the latest version, I suspect the GrapeCity.ActiveReports version 17.0.3 is not compatible with VS2022 version 17.8.7, and you can roll back the VS2022 to version 17.8.4 by opening the Visual Studio Installer > More > Rollback to previous version.
By the way, the package is related to GrapeCity, you can also report it in dedicated GrapeCity forum. Thanks for your understanding!
Sincerely,
Anna
