InvalidCastException：指定的强制转换无效。 （包装器castclass）Unity中的System.Object.__castclass_with_cache（object，intptr，intptr）

Question

I am trying to Instantiate a new Enemy from the enemy class and assign it to a variable of type Enemy. But I keep getting this error -> InvalidCastException: Specified cast is not valid. (wrapper castclass) System.Object.__castclass_with_cache(object,intptr,intptr) .

It points to this line -->

Enemy enemyTemp = Instantiate(enemyPre, new Vector3(-0.689f, 0f, 0f), Quaternion.identity); as the problem.

Most of it can be completely ignored, but I am declaring the var with this --> public Enemy enemyPre;

I put in a prefab of the Enemy inside this var inside the Unity editor itself. I'm using this method so I can reference the specific enemy later. I've tried many different solutions, but nothing seems to work. I find it odd because I did almost the exact same thing with the CameraFollow class and that works just fine. Does anyone have a solution?

I solved this problem by making sure the var was storing the Class and not the Game object itself inside the Unity editor.
