Hi Ravi Kumar Sah,
Welcome to Microsoft Q&A forum. I'm happy to help.
The error code 715-123130 often occurs when you try to download with the direct link, but it takes too long so the URL session ends before the download is completed, or download progress is interacted.
For convenience and stable download progress, please use the official Media Creation Tool.
Installing instructions can be found here: Windows 11 Clean Installation Process.
I hope that above information is helpful to you.
