[Bug] Windows - separate is getting stuck after about a minute into processing. Not hardware constrained.

• I didn't find a similar issue already open.
• I read the documentation (README AND Wiki)
• I have installed FFMpeg
• My problem is related to Spleeter only, not a derivative product (such as Webapplication, or GUI provided by others)

Description

spleeter separate runs, starts a bunch of python processes, starts ffmpeg, consumes a few GB of ram, starts writing the output files correctly, then just stops all activity forever. If I play accompaniment.wav, it is valid, it just cuts off at about 50seconds and never continues. The app produces no messages in verbose mode beyond the lines I pasted below.

The system has tons of RAM/CPU/Disk space available.

I've tried flac and wav, and tried limiting size with -d to no avail.

Step to reproduce

1. Installed using virtualenv w/ python 3.8, pip install spleeter.
2. Run as `spleeter separate '.\ARIatHOME - Let Me In.wav' -p spleeter:2stems -o $PWD --verbose
3. Got no error, but output incomplete and app runs forever.

Output

(venv) PS C:\Users\haze\Downloads\yt> spleeter separate -d 600 '.\ARIatHOME - Let Me In.wav' -p spleeter:2stems -o $PWD --verbose

Experiencing this issue too.

I'm also experiencing this issue. Windows 10, 32 GB of RAM, 3060. If I limit the input file to be a bit on the short side (let's say 15 seconds), everything works fine.

To confirm this is a Windows-specific bug, I installed Ubuntu 22.04 on my machine and spleeter now functions perfectly.
