When will the Russia-Ukraine war end?

[Storr]

End as in officially ending with a peace treaty and/or other binding agreement or, like the War in Kosovo, ending where there's a halt to active fighting, but no official end to the conflict and continued tension with occasional flare ups?

The former: Definitely only after Putin is dead or no longer in power. He feels that it is his historical mission to keep Ukraine in "the Russian World", meaning he has no interest in ending the war. Even post-Putin, a Korea-like freezing of the then current conflict lines might only be what's agreed to.

The latter: Sometime after the 2024 US Presidential election; Russia clearly hopes a second Trump term would give them an end to the war in their favor. Neither side feels it's in their interest to agree to a ceasefire at the moment and I'm not sure when that might change. Maybe if Western support to Ukraine wanes, forcing them to accept the then current geographical "reality"?
