I think there'll be a massive increase in energy prices due to the sanctions against Russia, which will make proof of work crypto unfeasible, so I don't think crypto will have a large enough marketcap to be a viable way for Russia to circumvent the economical sanctions

Proof-of-work cryptocurrencies automatically adjust to use as much energy as possible (the amount of energy which can be bought with the block reward and fees acts as a cap, and the incentives are to increase the amount of energy used until reaching that point). If energy prices increase, they will adjust by using less energy. This has no effect on the block sizes or block intervals, so the feasibility or lack of it of any mainstream cryptocurrency will be unaffected.

Well, block intervals will be affected until the difficulty parameter adjusts. But not the end of the world.
