This is weird. Editor scripts are normally automatically stripped from the build by Unity. Are you using asmdefs? If so, removing them solves the issue? If not, do you have other editor scripts (in any folder named Editor) in your project? Try making an editor script that references the namespace UnityEditorInternal and see if it builds or not.
