Async File Save Await does not "Await"

I apologize if this is a dupe. I couldnt find anything that dealt specifically with my issue. Im trying to save a file using "await SaveAsync". I get this error Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) I assume its because it attempted to move on before an action completed... but shouldnt it wait because I used "await"?

Here is my code

try
        {
            if (CurrentFile == null || !_existingDocument)
            {
                await _generateDoc();
                return;
            }

            var docGen = new CustDocument(_inputs);

            docGen.Save(CurrentFile);
        }
        catch (Exception ex)
        {

            throw;
        }

And my method

 private async Task<StorageFile> _generateDoc()
    {

        var docGen = new CustDocument(_inputs);
        var savePicker = new FileSavePicker();

        savePicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
        savePicker.FileTypeChoices.Add("dptx File", new List<string>() {".dptx"});
        savePicker.SuggestedFileName = _inputs.CustomerName.Replace(" ", "").Trim();

        var file = await savePicker.PickSaveFileAsync(); // Error here

        docGen.Save(file);
        return file;
    }

FOUND IT! Here Using FileSavePicker with MessageDialog's IUICommand event

Would have never thought that it had to do with the dialog box. To all who responded... Thanks for the help
