edit page visual not working


When I try to edit a page the "visual" is not working.

Before I was used to copy&paste text with images as well but now as the "visual" is not working I can paste only text and also then the visual is not working.

I am not sure since when this is happening maybe since the new wp version I assume.

Please see the screenshot.

You can see that after entering some text then going to visual is showing nothing.

Is there a way to make the visual working again?
