Russia is in some danger of wrecking its own economy. Putin is a clever guy who employs a lot of other clever guys, and will certainly know the risks, the question is more about what he can and can't do to improve matters without compromising his own position. Russia has actually been moving up the ease of doing business index, which might surprise people who only ever look at the less boring media. But it has a lot of other problems as well.
Oil and gas is great for centralized states. It's easy for governments and oligarchs to control compare to, say, a well diversified manufacturing base full of new products. But Russia's oil output is compromised by a lack of investment, taxes are very very high on oil profits and you always face the danger of having your assets seized. There's going to be a big questions over whether the Russian government is going to divert money it'd like to spend on popularity in to its own oil investment, and/or whether it can attract foreign investment (and possibly expertise). This is the same sort of problem Venezuela had, except Hugo Chavez was far more stupid about it (he took so much money from the state oil company to buy popularity that its output fell through lack of investment, and he sacked a huge chunk of his oil expertise out of spite after a strike).
Meanwhile, a centrally controlled economy run by governments, oligarchs and local pet thugs who steal what they can is never going to be too good at innovating with new products and methods. The current war is making Putin very popular, and so presumably less dependent on other support and more able to do something about this....for now.
A strong oil industry can make life hard for other industries if you have an open economy - local manufacturers can find themselves producing products which can be obtained much more easily by digging up a little oil and swapping it internationally for foreign goods. Oil sanctions would certainly help other industries develop more quickly....but I suspect those industries wouldn't operate very well.
It's certainly naive to write off the Russian economy, it's amazing how well problematic economies can product....but it's always going to be limited by its dysfunctional politics and state, which will never be tackled as long as Putin (or his heirs) is there.
