I have been having the same issue. It’s a long sequence with loads of different types of media that I am trying to export. I tried everything. Cleared cache, consolidated project, moved project from hard drive to computer, different export settings, in Premiere and in Encoder, etc.

I FINALLY tried unnesting a clip. It was a clip with a warp stabiliser effect on it. It worked. I noticed that it kept having an error in the same place (though there were a few outliers that threw me off). The clip had some diagonal lines at the end where the nested sequence isn’t as long as the clip in the main sequence (I had some media overlaid in the track above and didn’t notice), and I am yet to retest it with the clip properly trimmed, but Nesting seems to be a common cause, judging by previous responses. This is frustrating, because the nature of my work means I am constantly using nested sequences in my work, and I wish they were more stable. Would have helped if the error message was a bit more informative!
