I tired this lesson and now i have all types of things happening

[Brian_Kennedy]

Mr fireballs do not disappear anymore. my enemies are not taking damage and i have no popups showing.
im also getting an error that the given key grunt i was not present in the dictionary.

I also am not sure how to add my prefab for damage spawning I have a newer version ad i have three drop downs.
I cannot add my prefab either.
These are my errors :

The Grunt not present in the dictionary would seem to indicate that there is no CharacterClass.Grunt with stats in the progression prefab. Did the entry accidentally get deleted?

The ObjectReference Not set to an instance of the object is in the Fader.
If you look in Fader.cs, you will likely find a method

void Start()
{
     canvasGroup = GetComponent<CanvasGroup>();
}

When initially loading the game, there is a race condition where FadeOutImmediate() is called BEFORE Start().
Change Start() to Awake() and this should fix the issue.
