Project Stuck When Rendering or Exporting both in Premiere and AME

So I have a 30 minute video - nothing insanely complicated, 5/6 different camera sources, some 4K, some 1080p, all imported in a 30FPS 2K sequence. Edited with proxies, all dandy, go to export and I cannot get it to export. Everytime I export is gets stuck on a different %, tried with AME and same of it getting stuck at certain points, but never fully consistent where

Thus far this is what I've tried:

- Checking if the export catches on a certain clip (it doesn't)

- Changed export settings - everything from my normal preset to just match source high bitrate

- Global muted all FX

- Tried rendering in to out of different sections of the video - sometimes this works for part of it, sometimes it doesn't, sometimes a section that rendered fine will then get stuck when trying to render again

- Reverted back to previous update of Premiere

- Clean install of Premiere

- Cleared Media Cache

- Tried rendering just the original video sources in their native sequences - still tripping up randomly

Really at my wits end now - everytime it gets stuck I have to force end the application via task manager and I'm going to start seeing if I can export it one minute at a time to see if I can find the problem clip that way but I'm not convinced there is one at this point.
