Hello @BikramGc ,
Welcome to Microsoft Q&A forum.
The Visual Studio Community edition is supported only on the Current Channel, which means only the latest version is supported or available for downloading(kindly see this document: Community edition support for details).
Changing the catalog doesn’t work, as the previous version of Visual Studio 2022 Community is not available(for downloading).
It’s recommended to use the latest version of Visual Studio 2022 Community for learning purpose. If you have some particular reasons and have to use the 17.7.4 version of Visual Studio 2022, do you consider using Visual Studio 2022 Professional(17.7.4) or Visual Studio 2022 Enterprise(17.7.4)? They are available here: Fixed version bootstrappers. By the way, you can evaluate a free trial of VS Professional or VS Enterprise for 30 days and sign in to extend the trial period to 90 days(Extend a trial version or update a license).
Best Regards,
Tianyu
