Compute Head Movement from Speech Freeze/Hang

[俊之5FF9]

For some reason whenever I use this function, the system will reach halfway or sometimes 2/3 progress, and stop. Even after leaving my computer for hours there is no progress, and I have to close Character Animator using the end task function. Lip sync works fine, and my other computers seem to work fine as well. I'm not sure how to check what is wrong. Thanks for any help!

Have you tried using it with another character?

Yes, I actually did, and all of them freeze nonetheless. I've also tried different track length (30sec, 1min) and file type (mp3/wav). Apparently the only time it works is when I use anything under 5 seconds...
