black screen when the audio overlay goes to finish

            let voiceResource = AVAssetTrackResource(asset: asset)
            
            if videoTimelineView.duration <= ((voiceOvers[currentVoiceOver]?.startTime ?? 0.0) + asset.duration.seconds) {
                voiceResource.selectedTimeRange = CMTimeRange(start: .zero, duration: CMTime(seconds: asset.duration.seconds, preferredTimeScale: 10))
            }
            item.identifier = voiceOvers[currentVoiceOver]?.name ?? ""
            item.startTime = CMTime(seconds: voiceOvers[currentVoiceOver]?.startTime ?? 0.0, preferredTimescale: 10)

your issue maybe because the audio time is bigger than the video time, you can try to cut the audio time or extend the video time

@vitoziv thank you for answering, as you can see here I already do the selected time range

            if videoTimelineView.duration <= ((voiceOvers[currentVoiceOver]?.startTime ?? 0.0) + asset.duration.seconds) {
                voiceResource.selectedTimeRange = CMTimeRange(start: .zero, duration: CMTime(seconds: asset.duration.seconds, preferredTimeScale: 10))
            }

in case the audio is bigger than video, but I would say that's it's not because sometimes it's works and sometime I get black,

you need to know that i had more than one audio recorded and all have startime, but the only voice which reach the end can make the black issue
