Can't run rqt after removing plugin package

I've been trying to make my own rqt plugin. After a lot of back and forth, I finally got it to build. The problem now is that rqt won't run. I get the message listed below. In the last line, rqt_mypkg is listed as Key error. This is a package I had once before, but is deleted from my workspace now. I've tried cleaning and deleting my workspace, removing and reinstalling rqt, removing and reinstalling ros but nothing works. Rqt still won't run. Anyone have any idea what is wrong?
