Having the IP is one thing, having the means to build and launch is an entirely different kettle of fish.
Russia has used up all of the the rockets it held in shuttling people and vital stuff to and from the ISS, following the demise of The Shuttle. Russia has no more rockets available. That means that Russia will have to build something new. Methinks that in itself is going to take at least until 2030 (given how long it's taken SpaceX to about succeed) - if Russia can afford it (which I doubt).
So I take this announcement as another lot of grandstanding of which nothing serious will come. To build a rocket you need boatloads of money and experienced workers and engineers. Russia still has its oligarchs (although there have been some mysterious disappearances lately), but they cannot do business in the West and their holdings have been confiscated, so they can only rely on local currency and business. Said business is not going to be flourishing because of all the men Putin has sent off to die on that "special military operation", and of all the men that have fled the country to avoid being part of that shit. That's a nice big dent in the market right there.
Then there's the know-how. I'm sure that Putin's Russia has carefully avoided sending off Roscosmos engineers to the Front That Isn't, but I'm also convinced that many savvy artisans didn't get that chance. Building a rocket, or any major scientific project, is an ecosystem, and Putin has gutted that ecosystem to serve his stupid ideals.
Russia is not going back to space on its own. There, I said it.
