Except the 2014 sanctions have not ended and Russia had been cutting ties with the West ever since then. New sanctions might be harder but Russia is also much less vulnerable to them.

I am sure the sanctions will hit hard people who still have ties with the West e.g. people working for the Western companies or doing business with Western companies but I don't see how this can affect Russia's military capability. Some "model" not getting paid from Instagram/OnlyFans is not going to slow down military production and deployment.
