Open Utau closes when changing voicebank

🐛 Describe the bug

Open Utau closes spontaneously when changing voicebanks in the same UST. Before you think it's something from OTO or the voicebank, I tested the same bank in another project and it didn't close spontaneously. Below is the generated LOG file and a demonstration video.

Explains how to reproduce the bug

1. Open a UST or create your own.
2. Choose a voicebank to work with.
3. Replace that voicebank with another one.

OS & Version

UBUNTU STUDIO 24.04

Is your pre-rendering on? If yes, turn off pre-rendering and see if it still crashes

Hello! I disabled it in preferences and I can change the voice bank, but I can't play the new voice bank. When I click play, Open Utau closes like other times. Here is the new log:

Then this might be an oto or audio format issue. You can run a singer error check on your latter voicebank. (In "Tools → Singer", choose the singer you're using, "⚙→ Generate Singer Error Report")

I checked the errors indicated in the voice bank reports and the software no longer closes by itself when changing the singer. However, the project closes if I start playing the sound using the WORLDLINE resampler. Here is the new LOG file:

What does the singer error report say?

It could be (from what I could vaguely tell in the log) that certain samples in your voicebank is causing the crash. Check the bitrate on the samples and see if there's any inconsistency. It's recommended all samples should be in 44100Hz 16-bit.

Also, check the oto for any issues, I would do this in Vlabeler or whatever you're comfortable with.
