Corrupt Timeline/Sequence
Hello all,
I have been having a lot of issues this week with Adobe Premiere 13.0.3, and have been able to fix most of them up until this point. However; I have project that has a timeline sequence that seems to be corrupt. I can't alter the timeline sequence in anyway by duplicating it, or copying the assets from it or playing it back, or anything else.
If I try to do any of these things, it brings up this box -

Everything else within premiere seems to work fine. I've tried many things. I've tried exporting the timeline as an xml, uninstalling and reinstalling the software, going back to an old version of the software, tried using a different computer with a different OS, but have had no luck.
I'm currently running on a 2015 15" Macbook Pro with MacOS Mojave.
Any advice or tips and tricks would be much appreciated. At this point it seems I might have to start from scratch which would be a big bummer and a loss of over 50 hours of work.
P.S. It is only a problem with this one project.
