I‘ve been using adobe premiere pro CC on the same computer for 2 years now and suddenly am experiencing issues. A few days ago I was editing a project and suddenly the play head dissapeared and the entire program was extremely laggy. After hours of troubleshooting I made a new project and the problem went away. It’s like the project was corrupt or something.

But the main issue I’m having now is when I watch my project before I export, it plays back fine and looks great. Then after I export it and watch the finished video, it has tons of glitches. fragments from the sides of the videos flash and get big. I don’t know how else to explain it than to just say it glitches. This started three days ago and the same thing happens on every new project I make. It basically ruins the videos. Any help would be amazing.
