Media Encoder gets stuck when creating Proxies and final exports.

I have been having a problem for a while now when creating proxies they would get stuck. Same thing happens with some final exports. I am recording gameplay in 4K 60FPS using OBS Studio in .ts file formats with 6 audio tracks. This was working perfectly fine a while ago. But lately it hasn't. Disk usage is between 5-25 when exporting but when stuck it sky rockets to 85-95%. Any help would be appeciated.
