    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.

    Hi everyone I am Emily Naomi wanna give a big thanks to this wonderful psychic for bringing my husband back to me… I never really believed in magic spells or anything spiritual but a trusted friend opened my eyes to the truth about life. My marriage was heading to divorce a few months ago. I was so confused and devastated with no clue or help on how to prevent it, till I was introduced to this psychic Priest Ray that did a love spell and broke every spiritual distraction from my marriage. A day later my husband started showing me love and care even better than it used to be, he’s ready to talk things through and find ways for us to stay happy. It’s such a miracle that my marriage can be saved so quickly without stress. You can also contact him for help by email psychicspellshrine@usako. net
