I have been having an issue in Vegas Pro 22 when I try to import a very long video file (59hrs) into the project the audio goes mute about 1/3 into the video file. The video runs just fine it's just that the audio gets muted. I have never had this particular problem before even though I have done this exact same thing multiple times before.

So I got the new Vegas Pro 23 instead hoping that that would fix the issue, but it's the same problem. I have already checked the enable legacy AVD decoding box and that does not make a difference. The file is a mp4 avc file and the audio is H.264 48.000 kHz.

If anyone has the solution to this I would be eternally grateful! Hoping for a quick response <3
