Random messy sound wave, flashing back, and huge crack sound when installing a new voicebank

Recently I bought a new voice bank which is the “Shian” bank. However, after installing and activating it, when I try to create notes with this voice, the software always flashes back immediately. Also, as the picture shows, the audio wave that it created contains a lot of random and messy leaps, and when I click play, there is a huge crackle sound happened. I tried to uninstall and deactivate it several times, but it still happens. But I don’t have such problems when I installed other voice banks before.

Does anyone have this kind of issue before? How to fix it?
