    ACEMONSTER's `editorWindow.Close()` suggestion fixes the crash for me.

    Sometimes happens to me when clicking on a button from a custom DisplayDialog started from a PopupWindowContent. Here are the crash logs:
    ```
    <RI> Initialized touch support.

    Dereferencing NULL PPtr!

    This problem also reproduce on 2021.3.18f1,but is solved from me use a tortuous way.
    By test,if you close POPUPWINDOW before open EDITORWINDOW,this problem has never reproduced.
    Example:
    if (GUILayout.Button("打开窗口"))
    {
    editorWindow.Close(); //Important
    OpenWindow();
    }
    the crash info is "Dereferencing NULL PPtr!", so i think this problem is cause by the reason that popup window is not closed properly when new window opened and lost focus.
