Access Denied exception being thrown in UWP

Question

I'm trying to save a video file to a specific folder location instead of a library; which is what it defaults saves to. I'm using StorageFolder.GetFolderFromPathAsync to get the location. When it reaches that line in the function it'll throw the exception. 'Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))'

 private async Task StartRecordingAsync()
        {
            try
            {
                // Create storage file for the capture
                var videoFile = await _captureFolder.CreateFileAsync("SimpleVideo.mp4", CreationCollisionOption.GenerateUniqueName);
                var encodingProfile = MediaEncodingProfile.CreateMp4(VideoEncodingQuality.Auto);

                // Calculate rotation angle, taking mirroring into account if necessary
               

                Debug.WriteLine("Starting recording to " + videoFile.Path);

                await _mediaCapture.StartRecordToStorageFileAsync(encodingProfile, videoFile);
                _isRecording = true;
                _isPreviewing = true;

                Debug.WriteLine("Started recording!");
            }
            catch (Exception ex)
            {
                // File I/O errors are reported as exceptions
                Debug.WriteLine("Exception when starting video recording: " + ex.ToString());
            }
        }

Code in between

   private async Task SetupUiAsync()
        {
            var lvmptVid = await StorageFolder.GetFolderFromPathAsync("C:\\Users\\Nano\\Documents\\lvmptVid");
           // var videosLibrary = await StorageLibrary.GetLibraryAsync(KnownLibraryId.Videos);
           // var picturesLibrary = await StorageLibrary.GetLibraryAsync(KnownLibraryId.Pictures);
            // Fall back to the local app storage if the Pictures Library is not available 
            _captureFolder = lvmptVid;
        }

I've tried using different saving techniques, currently in the process of revamping the process. I've tried using a public file location instead of a user specific one.

When you are trying to use GetFolderFromPathAsync to get the file directly using a path, please make sure that you've enabled the broadFileSystemAccess capability in the manifest file.

Like this:

    <Package
xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
  IgnorableNamespaces="uap mp rescap">

<Capabilities>
    <rescap:Capability Name="broadFileSystemAccess" />
</Capabilities>

Please also remember to enable the file system settings in Settings > Privacy > File system.
