Answer 1

It seems that in one of your scripts you use AssetDatabase which belongs to the UnityEditor namespace. It exists only inside the Unity Editor.

In a build the namespace UnityEditor does not exists -> You can't use anything of it in a built application!

So after beeing aware of that there are basically to solutions how to fix those errors when using e.g. custom editor scripts or some code blocks that shall only exist inside of the Unity Editor but not in a build:

1. Either make sure all scripts that are only editor scripts are placed in folders called Editor. Unity automatically excludes those in a build.

2. Or use the #if pre-processor with UNITY_EDITOR:

   #if UNITY_EDITOR
       using UnityEditor;
   #endif
   
   ...
   
   #if UNITY_EDITOR
       //some code here that uses something from the UnityEditor namespace
   #endif
