Premiere Freezing And Crashing During Encoding at 0%

When I try to export (H.264/high bit) it renders the handful of audio files then switches to encoding and immediately stops at 0%, freezes, and then stops responding and must be closed. I've tried rendering effects, turning various plugins on and off (all of which I've used successfully before), and even just exporting the first 10-15 seconds which also freezes and crashes in the same way. I've tried the marker trick (I have none), copying and pasting into a new project and sequence, turn the gpu accelerator on and off, changing codecs and exporting formats and everything ends exactly the same. I'm completely befuddled on what is happening and would appreciate any help. It's barely a 3 minute video with a fair amount of fx, but I thought that would be a problem with rendering, not encoding. I've also reinstalled the previous version of PP at 14.6 since that is the version I started on, but the problem occurred in both 14.7 & 6.
