I can't click anything in my timeline/work bar

[XenoEditPS]

Please help me, my premiere pro was doing just fine. Suddenly I can't click/drag/move anything in the timeline/work bar, I can't alt + drag to copy, I can't do anything. It's like lagging but it's not. But I can still play the video just fine.
