Cannot export to H.264 - "Error compiling movie"
I have a complex project that Premiere Pro fails to export to H.264 every time. I have tried various settings, software/hardware encoding, clearing cache files, etc. Using very latest version (13.1.5 build 47). It failed with a prior version as well (hard crash of the application). Here is the failure with hardwared encoding (Intel HD Graphics 630), after 40 minutes of encoding:

I look at 4:09 in the video and there is nothing special there - no effects changes, keyframes or anything.
Tried software encoding (which oddly, ran 2X faster, but still failed):

Failed at a different point, but again, nothing special going on in any of the tracks.
So now what? Maybe some other format will work (maybe not), but how do I fix this so I can directly create H.264 like this product is supposed to do?
This is fustrating to say the least...
