はじめまして。Unity初心者です。
Vurofiaを使ったARを作成しようと思いまして
最初Win10で作成していまして、Androidでテストしてみて問題なく動きました。
Windowsではエラーは出ていません。

それをiPhoneでテストしたかったのでmacで開き直してビルドしようと思ったのですが
ビルドの段階でエラーが出てしまいます。

下記のようなエラーウインドウが開きます。

Copying file failed
Build completed with a result of 'Failed'
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

コンソールに出てくるエラーメッセージは下記の３つになっています。

Script attached to 'Boar_walk2' in scene 'Assets/Scenes/nengajou2019.unity' is missing or no valid script is attached.
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

以上のエラーが出てしまっています。
何かしらのチェックボタンを入れ忘れてるだけなのかもしれませんが
原因不明のため、unity(2018.3.0f2)とXcode(10.1)も再度インストールし直しました。
macOSもバージョンアップしまして、10.14.2にしてみましたが変わらずでした。

Windowsから持ってきたファイルが原因かと思い、macの方で新規シーンを作り適当なCubedだけのシーンでビルドしようと思いましたがまた別のエラーが出てしまいます。

長々とすみません。
何らかのパスが通っていないようなエラーに感じましたが、解決方法が見つかりません。
検索してみましても似たようなエラーがなかったのでこちらに投稿させていただきました。

よろしくお願いいたします。
