Files corrupted after failed wordpress update

I recently click the update button to update my version of wordpress, and for some reason the update failed and I now get this error on the page above.

I have tried pushing the same file up locally, but that hasnt worked.

I had the same problem with the website, I cant remember what file I needed to push up from local but it fixed it on the front end, but its not workign on the back end.
