If register the UpdateProgress event of ShellFileOperations, the operation will be invalid

[zhuxb711]

Describe the bug
If there is no following line, the operation is performed normally

 Operation.UpdateProgress += Progress;

If I register for the UpdateProgress event, the copy operation will be invalid. It means that no files are copied.

By the way, I want to know whether it is correct way to get the copy progress?

What code is involved

        public static bool Copy(IEnumerable<string> Source, string DestinationPath, ProgressChangedEventHandler Progress)
        {
            try
            {
                if (!Directory.Exists(DestinationPath))
                {
                    _ = Directory.CreateDirectory(DestinationPath);
                }

                using (ShellFileOperations Operation = new ShellFileOperations
                {
                    Options = ShellFileOperations.OperationFlags.AddUndoRecord | ShellFileOperations.OperationFlags.NoConfirmMkDir | ShellFileOperations.OperationFlags.Silent
                })
                {
                    Operation.UpdateProgress += Progress;

                    foreach (string SourcePath in Source)
                    {
                        using (ShellItem SourceItem = new ShellItem(SourcePath))
                        using (ShellFolder DestItem = new ShellFolder(DestinationPath))
                        {
                            Operation.QueueCopyOperation(SourceItem, DestItem);
                        }
                    }

                    Operation.PerformOperations();
                }

                return true;
            }
            catch
            {
                return false;
            }
        }

Expected behavior
Copy files and report progress

This is the correct way. There was a bug which is now fixed that threw an exception thus causing the operation to not complete.

When will a new version with this fix be released? Looking forward to your release.
