Can't edit a simple shape

I'm having a problem with the points on a shape not showing up or selecting. Hence, I can't edit it. The black arrow will select the object and when I use the white arrow for direct selection tool it doesn't seem to select it, although I can move the shape around.  Is the problem in my computer?  I was having trouble clicking on email links, but I have the same trouble when I changed the mouse.  I'm on a mac OS using Catalina and Illustrator 27.9.4.

Ideas?
