我正在将浏览器集成到我的软件中。当我继续打开新的浏览器选项卡时它正在工作，但是一旦我关闭一个选项卡并尝试打开新的选项卡，它就会在以下代码中产生异常。

public async Task InitCore()
{
    try
    {
        // Initialization.
        await webView.EnsureCoreWebView2Async(null);
        // This line gives exception if I close a tab and reopen as it gives exception in Initialization.
    }
    catch (Exception ex)
    {
         Enumerations.WriteToLog(Enumerations.LogType.Misc, "Browser.InitCore " + ex.ToString());
    }
}

// Subscribing events.
private void AfterCoreReady(object sender,EventArgs e)
{
    label1.Visible = false;
    this.webView.CoreWebView2.ContentLoading += webView_ContentLoading;
    this.webView.CoreWebView2.NewWindowRequested += webView_NewWindowRequested;
}

关闭选项卡后重新初始化时出现以下异常：

CustomWebView2.OnEnter System.Runtime.InteropServices.COMException (0x8007139F):
