the original code attempted to add every parsed enum to the project without checking if it contained any values. It also did have handling for the possibility of duplicate enum item names within the same enum on load which could also cause crashes.

Duplicates:

Adding a duplicate key to a Dictionary throws an argumentexception, leading to a crash. The code change checks for the existence of a key before adding it. If a duplicate key is found, the value is updated.

Empty Enums

Before adding an enum to the project, the code change checks if the values dictionary associated with the enum is empty. If it is, the enum is not added to the project. This prevents the creation of empty EnumDescription objects, which would lead to errors.
