Gore, Carnage, Hell - At Doom's Gate

This video got delayed three times already at late 2019, a bit before doom eternal's release, then just a few days ago. there was a huge problem with the audio because for some reason it got static at the 0:40 mark even though the sound for the entire video was fine when I was editing. I tried fixing it by replacing some of the clips and turn down the number of those clips after the 0:40 mark. which made it mostly better but the problem is still there. if anyone knows that have watched the video and uses Openshot that knows how to fix the problem please let me know.
