Is there some kind of error in OG on this site? Because for some reason there is no picture and description in VK.

Answer 1

OG is cached, usually every social network and others have a page to reset this cache

Answer 2

Clear the cache on the desired social network. A specific page is cached, the preview of which was created, for the test you can try to publish another page and see its preview
