不调用 CefSharp 初始化

如何解决不调用 CefSharp 初始化

我现在已经运行了十份程序。四个被冻住了。请解释为什么不调用 Cef 初始化

     private static ChromiumWebbrowser _browser;

     public static void Initializebrowser()
     {
        Console.WriteLine("Initializebrowser() -> start");
        if (Cef.IsInitialized)
            Console.WriteLine("Initializebrowser() -> IsInitialized");

        Cef.Initialize(new CefSettings(),performDependencyCheck: true,browserProcessHandler: null);

        _browser = new ChromiumWebbrowser();

        AutoResetEvent waitHandleOnbrowserInitialized = new AutoResetEvent(false);

        EventHandler onbrowserInitialized = null;

        onbrowserInitialized = async (sender,e) =>
        {
            _browser.browserInitialized -= onbrowserInitialized;
            Console.WriteLine("Initializebrowser() -> -=onbrowserInitialized");

            waitHandleOnbrowserInitialized.Set();
        };

        _browser.browserInitialized += onbrowserInitialized;

        Console.WriteLine("Initializebrowser() -> +=onbrowserInitialized");

        waitHandleOnbrowserInitialized.WaitOne();

        Console.WriteLine("Initializebrowser() -> finish");
}
