PS not allowing me to access the drop down menus option (see screenshot)

As you can see from this screen shot, I am unable to click any of the options, and it is like this on all the drop down menus only having one or two things I can select.My PS kept freezing, so i updated the program (Oct 18 update) but now this has happened?
Not sure what to do as I am unsure if its PS broken or I'm not doing something. I've never had this problem before.
Hopefully someone can help!
Thanks
