Hello Subhajit,
Thank you for updating me with that information. It may just be a bug and this could be resolved in the new updates in next week Patch Tuesday.
If you decide not to wait, Please try to Perform a Repair Install of Windows 10 with an In-place Upgrade. It will definitely help in resolving update errors. Performing this can repair broken operating system files while preserving your personal files, settings and installed applications.
**Few things to check on the PC
- Important: Back up your personal data and files to an external hard drive, USB thumb drive, or cloud location (such as OneDrive).
- Ensure you are signed in or have administrator rights to do a repair install
- Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
- Disable or uninstall any 3rd party Anti-Virus program to prevent it from interfering with the upgrade
Kindly try to use the media creation tool.

It might take some time to install Windows 10. Your computer will restart a few times, Make sure you don’t turn off your PC.
Kindly let me know if this helps or if you have any further concerns.
