Filter Bin Content not working


Whenever I try and search something in my imported media box, nothing comes up. Has never happened before so Idk what's causing this/what happened.
I've looked through here adn the only "solution", or better said workaround is trying to duplicate my project.
Would that literally just be, go to where I have my PRPROJ file saved, copy it and open the copy??
Having to scour through 700 files just to get what you want is not really efficient.
