Adding files stops me from being able to edit my project
I'm not sure if this is a bug so I'm hoping that someone can tell me if I'm doing something wrong. I've recently been having an issue where I will be editing a video and I go to add a file. If I add a file, I can no longer edit my project. The program doesn't crash, but it does not allow me to continue editing anything. I've never had this issue in the past so I'm not entirely sure what changed. Also, it doesnt matter what file type I'm importing. It applies to photos and videos as well. No error message appears at all during any of this. Its almost as if my project is frozen?
Please help.
