Hi, @Md Nasir Uddin

Thank you for posting in Microsoft Q&A forum.

The error message in your title is from wsyncmgr.log and it shows a sync issue.

This error message in your screenshot occurs during download. It could be due to a network issue or a problem with the update itself. You can try the following steps to fix it:

Check your internet connection and make sure it is stable.

Restart your device and try again.

If the error persists, try downloading the update manually from Microsoft Catalog using the URL from the update.
