Cannot close Window after opening another window modally

I have a problem. In my mac osx app I have a mainwindow. This window is opening initial. I am working with storyboard. But there are moments when the user needs to login again into the app. If this is the case (for example when the session ends) I open a new small window modally with this code:

private func openLogin() {
    loginController = self.storyboard?.instantiateController(withIdentifier: "LoginController") as? LoginWindowController
    guard let window = loginController?.window else {
        return false
    }
    NSApp.runModal(for: window)
}

after I once opened this window and close it again I can never close the main window. If the login window never opened, there is no problem and I can close the MainWindow. But if I opened the loginwindow once, I cannot close the mainwindow. I can click on the close button but it does nothing.

And, I cannot assure this but, I think that I cannot close any window after that.

Do you have any idea?

Thank you for your Help!

Ok, I have found the issue...

I called the code function openLogin() inside of the windowDidLoad() function of the NSWindowController. The problem is that the applicationDidFinishLaunching of the appDelegate will first be called after the windowDidLoad function finished, which is logically correct.

I stopped the mainThread by running a window modally. Somehow the framework doesn´t like this before the app has completed the launch process.

I solved this by using the NSNotificationCenter and observe the notification name NSApplicationDidFinishLaunching. On that I run the openLogin() code.
