editor build related issue in 2018.1

Been spinning my wheels all day trying to fix this error in my 2018.1 project. I did extensive search and everything indicated it was related to having a rogue script not properly excluding the 'using UnityEditor' directive from the script. I went through every bloody script in the project, and added the "#if UNITY_EDITOR" exclusion and the same error keeps appearing. Help, I've run out of options!!
The error message I'm seeing is this:

UnityEditor.BuildPlayerWindow+BuildMethodException: 2 errors
at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (BuildPlayerOptions options) [0x0021f] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:182
at UnityEditor.BuildPlayerWindow.CallBuildMethods (Boolean askForBuildLocation, BuildOptions defaultBuildOptions) [0x00065] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:89
UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)

 

Also, to clarify, I'm building into a directory completely separate from my Unity project assets, as I know others have had problems with that.

 

I recommend you look at the Editor.log file as Unity often outputs more detailed errors to the log that aren't written to the Console window in the editor.

Here is what I would do...

• Restart editor (to clear editor.log)
  
• Create a build (which eventually fails)
  
• Open Editor.log in text editor
• Search for "UnityEditor.BuildPlayerWindow+BuildMethodException: 2 errors"
• Scroll upwards in editor.log to see if any error was generated prior the BuildMethodException

 

Appreciate the response.
That file seems like it would be useful, although in this case, I'm not seeing anything jumping out.

Here is excerpt from that file (I selected 'Full' logging) showing immediately before/after the error:

Figured it out (finally). Found the error much further up in the log file. Had to do with a Windows Mixed Reality dll that couldn't be located.
