Lately, Premiere Pro has been frequently freezing on one of my projects. When I move/drag clips, crop them, or enlarge them, my screen will stop responding and become greyed out for at least a minute. (The shortest lags are for 20-30 seconds, but they can be longer than five minutes). While I have a lot of clips stashed in the project library, the actual timeline has less than five minutes of audio and video, so that should not be causing the issue. It got to a point where it took three hours for me to edit just a few seconds of footage. I tried importing the files into a new project, but it froze and crashed. So, I restarted Premiere Pro, clearing the entire media cache and resetting the preferences. It seemed to help a little bit, but it is still having issues.
My computer is only six months old, and I don't have a lot of programs running in the background. My other projects seem to do fine, although since I'm not currently working on them, they do not have as many clips. My university's WiFi is a bit slow, but Premiere Pro used to work just fine on my old computer last year.
Should I try importing the project again? Or should I just uninstall and reinstall Premiere Pro?
