Bug description

I am trying to manually extract frames using the napari GUI. Once I select a frame and press "Extract Frame" I am getting the following error message in the command window:

  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\napari_deeplabcut\_widgets.py", line 279, in _extract_single_frame
    _write_image(frame, str(output_path))
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\napari_deeplabcut\_writer.py", line 84, in _write_image
    imsave(
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\skimage\io\_io.py", line 143, in imsave
    return call_plugin('imsave', fname, arr, plugin=plugin, **plugin_args)
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\skimage\io\manage_plugins.py", line 205, in call_plugin
    return func(*args, **kwargs)
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\imageio\v2.py", line 263, in imwrite
    with imopen(uri, "wi", **imopen_args) as file:
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\imageio\core\imopen.py", line 113, in imopen
    request = Request(uri, io_mode, format_hint=format_hint, extension=extension)
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\imageio\core\request.py", line 247, in __init__
    self._parse_uri(uri)
  File "C:\ProgramData\Anaconda3\envs\deeplabcut\lib\site-packages\imageio\core\request.py", line 412, in _parse_uri
    raise FileNotFoundError("The directory %r does not exist" % dn)
FileNotFoundError: The directory 'C:\\Users\\mooney_lab\\Desktop\\labeled-data\\34_TP261_221223' does not exist

This is not true because the folder does exist. If I extract frames automatically it works normally. Is there a solution for this?

Thank you!
