Recently updated to Illustrator CC19 (version 23.0.1) Was altering the workspace and when I selected the Graphic Styles palette I get the error message "There is not enough memory available to process the appearance of an object error" Didn't even have an object selected or anything, after the error message all options are greyed out and I can't select anything on the artboard. Tried restarting, saving a new file, deleting all the graphic styles I had installed but the error still persists. This is happening for both old and brand new files.

I uninstalled Illustrator and reinstalled and it seemed to work temporarily, but when I opened illustrator a second time the error comes up again when selecting graphic styles.

macOS latest version all up to date. Late 2013 iMac.
