I'm almost sure that the video file was partially damaged when editing or copying to one or another device. I need more details to give more accurate information. So far, I can only assume that the software you used to edit the video simply corrupted its format or codec. I had similar cases in practice and that is why I switched here to using more expensive and high-quality software like Movavi.

I had the same problem when I installed a voice changer for discord, and I tried to fix this problem for a long time, but nothing came out. Then I called my friend, who knows the computer better, and he just deleted the old drivers and installed new ones, and he also reinstalled the discord and configured everything in the microphone settings. Well, somehow, if all these actions don't help you, then it's best to Google, and maybe you'll find what you need. Good luck to you, friend, you will succeed, man
