Sony Vegas Pro 13 won't open Multi Channel MP4 files.

So my friend uses the same settings,buttt when I import MY files, this happens https://gyazo.com/926a088ea462aa431d4a40dd40437d48 I have no clue what to do, I tried old solutions but none of them work. I also tried a non multi channel mp4 file. IT WORKED FINE! Its just the multi channel one. This is seriously screwing with my work flow! I can't use Premiere anymore because some of my gameplays don't have a constant 60 FPS. Seriously this is a big issue help!

Yeah im having the same issue, nothing seems to work. I record at 1080p 60fps mp4 NVIDIA NVENC with my mic being a separate audio track and I get 2 tracks of audio but no video. But when I record without my mic being a separate audio track it works fine. Hmmm
