Hello,
Ensure that the computer is connected to a stable power supply to avoid interruption of the update process due to insufficient or unstable power supply.
Make sure your computer is connected to the Internet and that the connection is stable.
Sometimes files in the update cache can get corrupted or lost, causing the update to fail. You can try to clear the update cache and then restart the update process. In Windows 10, you can do this by going to Settings > Update & Security > Windows Update > Advanced Options > Clear Update Cache.
Best regards
