I'm not a military expert, but it seems like this will benefit the Russians, who will now have time to reinforce and strengthen their positions in Kherson Oblast on the south side of the Dnipro River at a time when Ukraine has been gaining momentum, and possibly considering crossing for a counter-offensive.
From a purely positional perspective, this is a big advantage for the Russians, who benefit from a more prolonged conflict because they have more people, and need more time to resupply their logistics.
Ukraine needed to present a credible threat to cross there to pin Russian forces in the area. Now that it's basically impossible to cross the river, Russia can redeploy the majority of the forces to other areas.
Last fall, Russians have built and used several pontoon bridges over Dnipro for a few weeks, as they defended Kherson city and the Antonovskij bridge was rendered unusuable by HIMARS strikes.

Not great.
