Uncaught Error: Call to undefined function get_current_screen()

I have just added a new post to my site, and now every post or page has this error on it. Any ideas? There isn’t an update available at all, and it just started happening out of the blue. No new plugins installed, nothing updated etc.

Fatal Error:
