Russia's explicit and communicated goals for this war were utterly failed by day four of the invasion. Arguably they lost within hours when they failed to take Hostemel airport.

By Russia's own accounting, they lost years ago. It does not matter what the outcome is, Russia has taken massive pain to sustain this war they never planned to sustain. They entirely used up their immense Soviet inheritance, which was something they held in high regard and used to insist made them strong. It's gone now. Used up.

The gas station of Europe can no longer produce sufficient gasoline for internal use. It will take at least months to get that capability back.

They have utterly failed to substitute sanctioned components, having switched back to imported components after their internal substitutions performed so poorly.

Their navy is being taken apart by a country that scuttled it's own navy on day one. Ukraine sunk the flagship of the black sea fleet with supposedly just a few missiles, something which the Moskva by all accounts on paper, should have handled just fine. Except all their craft are in such poor condition that many of the systems on the Moskva were likely just nonfunctional, including defense radars, communications, and anti-missile defenses.

Russia was totally reliant on an American private company for their battlefield communications, and is not coping with the shutdown of their access, which they should have been prepared for long ago. They were also dependent on Discord and Telegram.

Russia is being seriously wounded by a country much smaller than it, which also ostensibly had all the same problems as Russia, like poor soviet doctrine, corruption, a poor economy, and demographic issues.

Russia is failing to compete industrially with a former vassal.

Russia had to import soldiers and ammo from north korea.

Russia's weapons export industry is dead. Nobody wants their trash that has proven terrible on the battlefield. Nobody expects Russia to actually be able to build what they claim to sell anymore.

Russia is so run dry on arms that they couldn't help Venezuela against the US invasion. They sent a single anti air weapon system.

Half a million Russians are dead.

If the war ends today and Russia is allowed to keep all the land it is currently standing on, it still has lost. It's not even a Pyrrhic victory at this point.
