Premiere hitting 100% GPU on H.264 and not exporting

Hi guys,

I am having an issue with Premiere Pro (14.8) where whenever I try to export a video that I have been working on, I get an annoying issue with my GPU instantly hitting 100% usage and after a couple minutes of it exporting (it usually hits 15-20% exported before stopping), Premiere freezes and struggles to shut down.

The video that I am trying to export incorporates a few cuts/transitions and animations, nothing too crazy, as well as some effects like blur and audio effects. There are a decent handful of video files that are in this file, and the final duration of the video would end up being 45mins (3.5GB H.264, 2.4GB H.265)

I have tried searching around but all I can really find when Googling the issue I am having is Google misinterpreting the question and giving me a bunch of links for turning on CUDA rendering (which I have already been using).

Any help would be greatly appreciated

Handy specs if needed:

Ryzen 1300X CPU

Asus GTX 1080 STRIX

16GB DDR4 RAM 3200Mhz

Video clips that I am working with are all stored on a 2TB Seagate Barracuda HDD
