Unable to add new slides

I had not created any new slides since 2014, but tried just now and when choosing featured image it will not update. The image does not appear in the backend or front and I am creating them just as I would have in 2014. I tried disabling any plugins that seemed to possibly interfere, but still no luck.

All my plugins and wordpress core are up to date.
