You mentioned that site was restored, but as we can see, images were not restored but re-added, in media library new images are displayed with new author, date, id – https://prnt.sc/1r1momx , but old images can’t be displayed not in the media library, not on the frontend. Products want to show old images, that were selected for them, so there are errors in the browser console – https://gyazo.com/6b178cd1977f98d76d4c75effba81e56 You need to contact person who helped you with the restoring, it looks like the restoring was done a little wrong and caused current problems.
