Unfortunately the situation right now is complicated due to sanctions. There's a possibility of just traveling to Russia and taking cash out of the country but obviously this is not ideal, you'd also need to declare it and back it up with documents showing it's not stolen.
The problem right now is that US banks are not working with Russian banks due to sanctions. There might be an individual US bank who still is, you'd have to contact each bank individually and ask them. As far as I know, it is being blocked from the US side, not the Russian side. So, any Russian bank would cooperate, you just need to find a US bank that would be willing to accept the transfer.
