No longer appears to work after update

I’ve just updated to WP v.5.7 and now when you click the image it opens the image location and there’s no way to close it. The user must click the “Back” button. I’m also running Divi v.4.9.2. Don’t know if it has been depreciated by Divi or WordPress. Since the class=et_pb_lightbox_image looks like a Divi class then I am assuming it is a Divi thing. Hope it can be fixed.
