When I export a GoPro sequence the estimated file size is large, but the resulting file is 1 byte

I just am trying to stitch the long GoPro video I took (it separated it out into 5 files) into 1 continuous file. The preview of the sequence and everything looks fine. Whenever I try to export it to 4k or 1080p, it results in a file that is only 1 byte and doesn't play. it still takes like 20 min to encode. 

There's not even any effects, i'm not sure what's wrong.
