When a description is not entered during the generation no description is given next to the key in the theme.info.yml file. This throws an error on admin/appearance.
The following error is thrown:
InvalidArgumentException: $string ("") must be a string. in Drupal\Core\StringTranslation\TranslatableMarkup->__construct() (line 140 of core/lib/Drupal/Core/StringTranslation/TranslatableMarkup.php).
Adding a description fixes the issue or removing the null description key from the info.yml file.
