If there is an economic sanctions that could stop Russian to invade Ukraine, they shouldn't have initiate the war.
Putin knew his country's economic capabilities and he knew who will stand by their side in situations like this.
So, I guess no economic sanctions can stop Russia from ruining Ukraine and yes they surely can survive it. Though people from Russia may suffer with their international relation in terms of businesses.
If Russia was ready then why is it limiting bank withdrawals and blocking people from exchanging rubles to foreign currencies? Why is it out of fiat money? I don't think they are ready and I don't think they can take the sanctions for a long time. Putin knew what he was doing but he underestimated Ukraine. He thought he'd get sanctioned but Ukraine will surrender by the time these sanctions can hurt Russia and then Russia will withdraw, taking Crimea and Donbas with it and the sanctions will begin to ease up.
If the war drags on for another month there won't be much economy left in Putinland.
