My understanding is that state owned enterprise has become very dominant in Russia after the start of the war, and a lot of private business is now being state directed. So, I think it's fair to say that the commanding heights of the economy are largely under state control now.
You are either ignorant of history or you have a different definition of what constitutes failure than normal people. State directed economies have been objectively the most successful model in human history for rapidly and as widely as possible improving material conditions.
What has failed in the past and continues to fail is actually the liberal economic model.
