Reproduction Steps

After upgrading CefSharp from 114.2.120 to 127.3.50 the multiple file download is not working

I am using the below angular code to download the xml file. Need to download 3 files.
this.serviceObj.saveTextAsFile(report1, report1);
this.serviceObj.saveTextAsFile(report2, report2);
this.serviceObj.saveTextAsFile(report3, report13);
saveTextAsFile(textToWrite: string, fileNameToSaveAs: string) {

var textFileAsBlob = new Blob([textToWrite], { type: 'text/xml' });
var downloadLink = document.createElement("a");

downloadLink.download = fileNameToSaveAs;

if ((window as any).webkitURL != null) {

  // Chrome allows the link to be clicked
  // without actually adding it to the DOM.
  var textFile = (window as any).webkitURL.createObjectURL(textFileAsBlob);
  downloadLink.href = textFile;
  downloadLink.click();

  // manually revoke the object URL to avoid memory leaks.
  (window as any).webkitURL.revokeObjectURL(textFile);
  downloadLink.remove();
}

}

Below is my custom Download handler code
public bool OnBeforeDownload(IWebBrowser chromiumWebBrowser, IBrowser browser, DownloadItem downloadItem, IBeforeDownloadCallback callback)
{
OnBeforeDownloadFired?.Invoke(this, downloadItem);

    if (!callback.IsDisposed)
    {
        using (callback)
        {
            callback.Continue(downloadItem.SuggestedFileName, showDialog: true);
        }
    }
    return true;
}

public void OnDownloadUpdated(IWebBrowser chromiumWebBrowser, IBrowser browser, DownloadItem downloadItem, IDownloadItemCallback callback)
{
    OnDownloadUpdatedFired?.Invoke(this, downloadItem);


    if (downloadItem.IsComplete || downloadItem.IsCancelled)
    {                

        if (isFileToBeOpenedByDefaultApplication(downloadItem.MimeType, browser))
        {
            if (browser.IsPopup)
            {
                browser.CloseBrowser(false);
            }
            if (downloadItem.IsComplete)
            {
                try
                {
                    var dg = new Action(() =>
                    {
                        MessageBox.Show(string.Format("{0} has been downloaded successfully to {1}", Path.GetFileName(downloadItem.FullPath),
                                    Path.GetDirectoryName(downloadItem.FullPath)), "File Download");
                    });
                    System.Windows.Threading.Dispatcher.CurrentDispatcher.BeginInvoke(dg);

                    Process.Start(downloadItem.FullPath);  
                }
                catch (Exception e)
                {
                    Logger.LogException("Process.Start Exception", e);
                }                        
            }

        }
        else
        {
            if (downloadItem.IsComplete)
            {
                var dg = new Action(() =>
                {
                    MessageBox.Show(string.Format("{0} has been downloaded successfully to {1}", Path.GetFileName(downloadItem.FullPath),
                                Path.GetDirectoryName(downloadItem.FullPath)), "File Download");
                });
                System.Windows.Threading.Dispatcher.CurrentDispatcher.BeginInvoke(dg);
            }
        }

    }

}

But only one file is getting downloaded. after that the download itself is not working. Please provide a solution

Converting to discussion as this is unlikely a bug in CefSharp.

There were major upstream changes recently. You can read about them in more detail at https://groups.google.com/g/cef-announce/c/s1WaovAopFo/m/LV5eiNX1BgAJStarting

Many behaviors have changed.

What version are you using? Please only open an issue if you can reproduce the problem with version 130.1.90 or later.

As per https://github.com/cefsharp/CefSharp/blob/master/.github/ISSUE_TEMPLATE/bug_report.yml

Have you tested the current supported version? At time of writing M131?

If it doesn't work in M131 then you can try switching to a Chrome Styled window. See #4835 (comment)

If that doesn't work then the best place to ask is on https://www.magpcss.org/ceforum/viewforum.php?f=6&sid=1eb1597a73e5c70e6211f420b9a10a60

Did you check the log file for errors?
