What are you trying to cut and paste? Is it text or an image or both?
Where are you trying to paste it to? A document or an image file?
If you are looking to save everything on the page you can try to “save as” another document type in another folder for editing later.
Something you cannot just cut and paste what you see unless you have special tools like Irfanview (Freeware), Snipping Tool or a similar application.
