Documents will not save to my MacBook Pro macOS Monterey 2021

When I select save the box comes up and the 'save as' option has a name in it and it will allow you to type in a new name and the Cancel button at the bottom is in black font and the save button right next to it is in a grayscale color and totally inaccessible. So you cannot opt to save it and when you hit the cancel button to exit, nothing happens. The only way to get out is to hit the escape button and the screen goes back to the document you are attempting to save. It will not save as or save. It just sits frozen :(
