🐛 Describe the bug

When trying to export my ustx to wav, it only makes 1 wav file (there are 3 singers so there should be 3) that is 0 seconds long and 46 bytes. I opened up the debug window to see what was wrong and when I try to export, it says "Set Progress 0 Exporting to (my folder)/export-01.wav. not on main thread. Failed to render." It wasn't like this a couple hours ago and I don't see what could've gone wrong? I've reinstalled OU and restarted my computer, neither worked

Explains how to reproduce the bug

1. Open Openutau
2. Click on Export Wav Files

OS & Version

Windows 10
