Possible null reference argument for parameter 'path' in 'DirectoryInfo Directory.CreateDirectory(string path)'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
