cached player destination differs from selected player destination

I’m a noob with Unity.
When I build my project, my character’s mouth doesn’t do anything when speaking. It works fine when testing in the Unity game window.
I get this error when trying to build project:
“cached player destination differs from selected player destination”

I have the same problem:

Error building scripts: Cached player destination differs from selected player destination. Please disable scripts only build and build again before attempting another scripts only build

Build completed with a result of ‘Failed’
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

UnityEditor.BuildPlayerWindow+BuildMethodException: Error building scripts: Cached player destination differs from selected player destination. Please disable scripts only build and build again before attempting another scripts only build
