Stuck on audio writing with multiple videos

[thirtwo]

Hello, I am new user so this can be unaccurate, but I think it's a bug. When I was writing one video it seems ok. If I try to concatenate more than one videos, it stucks on audio writing and gives this error: Code Snippet

//reading video files in for loop
video = mp.VideoFileClip(videoPath)
video.audio.write_audiofile("test.wav", 8000, 2)

// getting silence parts of videos in test.wav
// i think this part irrelevant but i can share if needed
clips = []
nullList = []
//cutting videos silence parts
if silence == nullList:  
        clips.append(video)
    else:
        for start, stop in silence[::-1]:
            clips.append(video.cutout(start, stop))


//trying to concatenate video clips 
finalClip = mp.concatenate_videoclips(clips)
finalClip.write_videofile("mynewvideo.mp4")
finalClip.close()

I encountered the same problem, have you solved it?

@jaysonteng I found a temporary solution. I was using Kali linux. I used the code on my windows devices. Sorry for not helping!
