Ok, I tried it again this time (second time without hls). Local processing is disabled although I tried to enable it once by switching to desktop mode when initially troubleshooting this error.
This time, I tried to keep the phone screen awake and on the download page as much as possible, which worked better than when I ran it before going to sleep and got a slight improvement in the amount of the video with audio, almost hitting the 50% mark.
Previous downloads showed 4.41GB (4.73 GB in browser) or 4.44GB (4.77 GB in browser) but this one got to 4.47GB (4.80 GB in browser) before stopping on its own. Also, sorry about the file names, they're a mess bc some of them were resurrected from the recycling bin.
