Does it all work well if you use example data sets shown in [this tutorial](https://github.com/NVIDIA/ai-assisted-annotation-client/tree/master/slicer-plugin#tutorials-and-examples)?

Does the `C:\Users\Split\AppData\Local\Temp\Slicer\slicer-aiaa2020-01-27_15+02+46.625\tmp7kbhpzha.nii.gz` file exist? Is it valid? Can you load it into Slicer by drag-and-dropping? (the file may be deleted automatically when you click OK, so try to make a copy of the file before clicking OK in the error popup).
