Cannot resize shapes, shift+cmd+B is not the solution
For some reason, my Illustrator will not let me resize shapes. Shapes made with the ellipse or rectangle tool. My work computer has no problem with this, so it is something specific to my personal Adobe.
I've tried resetting the bound box, that hasn't helped. I tried trashing preferences, also didn't fix it. I tried uninstalling and reinstalling Illustrator, still won't work.
I feel like I noticed the problem shortly after installing CC2019. When I launch Illustrator, it tells me Shapecoreui.aip plugin isn't working. I can't find this plugin on my machine, I can't find anything about it on Google either.
I've noticed my shapes have blue squares at the corners, and things I can resize, like text, have white squares. I feel like that is a clue to something, but I don't know what it is trying to tell me.
It's driving me absolutely insane.
