Premiere does have completely random export issues. Generally exporting uncompressed is the safest bet, but sometimes that comes out bugged too. Some people have had luck with exporting with UT Video as the codec, as well. A potential alternative is to export bit by bit, with seconds-long clips, and keep trying exporting a certain clip if it fails, until it's fine.
Yet another thing you could try is to open the project straight in adobe media encoder, while keeping premiere close. You should have File > Open Premiere Sequence or something of the sort in Media Encoder. At that point you can navigate to the project file and then select the sequence.
A final solution could be to try and export from after effects, as it is able to load premiere projects, but keep in mind that before doing that you might have to go around fixing conversion issues that could arise (afaik transitions don't translate well from premiere to after effects, for instance)?
