For some reason, Spleeter doesn't like outputting to a root folder like "D:"
Try "D:\output" that should work better.

Error "Can't load save_path when it is None" occurs when Spleeter fails to load the pre-trained model files.
The easiest way to fix is to close SpleeterGUI, delete the "pre-trained_models" folder and run it again.

The model files are quite large and can become damaged while downloading on an unstable internet connection.
Antivirus apps may interfere here too. Because this is a windows executable that runs a python command line that downloads stuff, antivirus can block that as malicious. if the model files refuse to download, you may have to run SpleeterGUI with admin privileges or exclude the SpleeterGUI folder from it (whitelist).
