could load default layout unity code example

Example 1: unity default layout error

1. Delete LastLayout.dwlt from C:\Users\YOURNAME\AppData\Roaming\Unity\Editor-5.x\Preferences\Layouts\default
2. Delete CurrentLayout.dwlt from C:\Users\YOURNAME\Unity Projects\YOUR_PROJECT\Library

Deleting both the LastLayout.dwlt and the Library/ before attempting to re-open the editor cleared up the issue.
