Exporting as Solid Green Video

So I edited everything as usual and went to export my video and after exporting it switched the color of all the video files to green. Everything else works, such as the titles I inserted and audio, even the pictures I have in the video appear. Its just that the video files are all a solid green color that take up the whole screen. I tried to go back into the project and the issue is now there too, where all my videos in the editing window are just solid green. I've tried reopening the software and everything I can think of, but no resolution.
