Yes having the same issue with both CC2019 Illustrator & InDesign !! This started today as I was working with these programs yesterday. I'm using High Sierra.... Does anyone recommend switching to Mojave OSX?? I heard there were some bugs there too from Apple's side. This seems to be an Adobe issue.
