When you double-click a library to view the contents, the following error may occur.
For example, the following error may occur when opening Documents library
Similarly when opening the Music, Pictures or Videos library
To fix this problem, open Windows Explorer, right-click on the corresponding library and choose Delete. Click Yes when asked for confirmation.
Note: Deleting a library does not delete the contents of the included folders. However, you may need to re-add or include your folders manually, if needed.
Then, in the navigation pane of Windows Explorer, right-click Libraries and click Restore default libraries.
This recreates the library that was deleted earlier. This option only restores the default libraries.
