I just downloaded a fresh install of Premiere Pro 2020 after performing a wipe and fresh install of Windows 10. The problem is that Premiere won't play anything now! I'm able to open the project and do things like move clips around and save the project, but if I hit the spacebar or the play button the program preview just stays black or gray. Even when I move the playhead around without playing anything, all I ever get is black or gray. I've checked my resource usage while trying to play things and it doesn't appear to be tapping into my memory or graphics card at all. Memory usage hovers around 2gb and the graphics usage stays at 0% no matter what I do.
I've also noticed that whenever I try to close the program it freezes and I have to end the task manually.
