Solution

Check and update the Windows operating system. Ensure that the network connection is normal before performing the following steps:

Click the Windows icon and go to Settings > Update & Security.
In the Windows Update window, click Check for updates.
Perform the updates if there are any.

Your files will not get lost during the update. However, you can back up important files to an external storage device beforehand.
If this issue persists, you are advised to manually update the system.
