GoPro Footage became unsupported in the middle of a project

I had started a project and imported all my footage, some of which included footage filmed on my GoPro Hero 6 Black in 1080 at 60fps. I know that GoPro footage and after effects have a shaky relationship, but I didn't think something like this could happen. Everything was fine and I edited the GoPro footage in my project and moved on and when it came time to render, I got the multicolor corrupted file bars in place of the two gopro clips. They were fine while editing but now don't work and cannot be imported at all. I now get the "this MooV file is corrupted or unsupported" message anytime I try to reimport the clips. Keep in mind these were imported earlier without any issue. Any ideas?
