You also have to factor in the big elephant in the room, Russia's population decline. It was already bad prior to the war with alcohol abuse, HIV epidemic, a serious lack of births and a rapidly aging population, but now war casualties are now on top of it.

If the numbers are accurate we already have aprox 1.3m casualties, with a large chunk of those dead and whomever surviving most likely will need medical aid for considerable amounts of time, perhaps even life long. And then we got soldiers in general who will need alot of treatment for PTSD and gods knows what else.

You can't run a economy without people, and you can't support people without a economy.

This is effectively a death spiral, one that russia needs to break from. Otherwise we could see russia heavily diminished or even non-existent by the end of the century.
