ultimatevocalremovergui: Crashing at "inverse stft of instruments and vocals"

Using GPU or CPU, it gets to “inverse stft of instruments and vocals”, hangs for about 30 seconds, then closes. This is on v2 and v4. I tried with the latest version of tsurumeso’s command line vocal remover and it works fine.

I’m using a GTX 1080ti, 32GB of system RAM, Windows 10. I tried with a clean install of both Python 3.8 and 3.7.

The console output: 100%|██████████████████████████████████████████████████████████████████████████████████| 42/42 [00:03<00:00, 11.34it/s]
