This version of Illustrator (26.1) on MacOS Monterey 12.3 is sporadically having problems with taking an object and using keyboard shortcuts to copy/constrain (option/shift). At seemingly random times when trying to copy an object with option held down or option/shift held down and dragging the object with the mouse, I am getting the error noise and then a rejection of what I was trying to do. It happens frequently throughout my workflow, but I'm not sure exactly what is triggering it. Sometimes I get the error noise when simply dragging an object around the artboard, but again seems totally random.
