Noise generated during regeneration

When playing music, it makes a shaking sound like a broken television. The more musical instruments you put in, the more noise you make. There was no problem with the sound of the metronome, but only the sound of the notes is strange. But when I played it on the website, the sound quality was really clean. So I deleted the MuseScore, reinstalled it, and restarted the computer, but it didn't work out. I'm sorry that I can't attach the file because the size of the video is too big. Please solve this sound quality problem.
