URGENT Premiere not allowing me to drag clips only audio

Hello, I'm a stressed college student about to fail a project because suddenly--Monday to be exact, premiere stopped allowing me to drag and drop clips into my timeline in order to edit. Instead, it'll show a hand with a circle and a line through it and only allow the audio of my clips to be inserted after inserting one clip. It's infuriating. I can't even begin to edit because I can't assemble anything. The only post similar to mine I found told me I couldn't access it? I have no idea what's up but it's really testing my patience. 

I already tried installing and reinstalling the app....no change. Attached is a video showing the issue.
