We recommend copying the following error message and providing it to the developer, then restarting the application.

Exception Details:
AggregateException_ctor_DefaultMessage (AggregateException_ctor_DefaultMessage (Error loading vocoder "nsf_hifigan_44.1k_hop512_128bin_2024.02"))

I have nsf_hifigan installed already. I was using Hitsune Kumi's DiffSinger AI and this happened. How can I prevent this from happening again. Also, whenever I open a .ustx , the app saves the project but crashes at first and crashes if I try open it again.

Download the vocoder(.oudep) here:
https://github.com/openvpi/vocoders/releases

And install it:
Singers > Dependencies(🧩) > Install

If Diffsinger make strange noises, try to increase the number of render steps in setting.

Are you sure you installed "nsf_hifigan_44.1k_hop512_128bin_2024.02"?

If not, please ensure you install the vocoder exactly required by your singer, or modify dsconfig.yaml (if the singer's ToS permits) to specify the vocoder you have installed.

Wait sorry. I have it now. How do I install it when it's in a zip format. Have I downloaded the wrong file?

You need to download .oudep file, not zip.
