You can't view them on gofile natively as far as I know, you have to download the 2 jfif images and open them in something like the built in windows photo viewer or paint etc.
They are legit files, here is a repost of the images in jpg format
as long as the vod isn't deleted on twitch's end you can always find the vod link, which is an m3u8 file
here is today's vod you can download it with TwitchRecover or other methods like VLC as well
