I recently encountered a major problem with Premiere Pro. I went to drag in video clips for my project, and while I can drag them in fine, the video itself won't show up and won't even play when I press space or click the play button. I thought it was just a glitch, but I have relaunched Premiere Pro and restarted my computer several times, only to have this issue remain. It even affects older projects of mine, ones that had video clips that played fine, only now for them not to show up, and to not play. The photos below are what it looks like for the two projects. This project is for a final for my college course, so advice to fix this as soon as possible would be very much appreciated.
