There can be no greater challenge to the rules-based order than a member of the United Nations Security Council flouting the most basic of international laws and, without provocation or attack, invade a neighbour using dishonest pretexts like an assertion that they're Nazis, when it's most obvious to countries like us that the Ukrainian Government was not a Nazi Government; using the pretext that they, Russia, had to do this for their own security, when there was no real threat from either the Ukraine or NATO to the territorial borders of Russia; and an attack on the rules-based order which, as other members have said, cannot be properly responded to through UN channels because the right of veto of UN Security Council members is relied upon by Russia to stymie the effort. The need for action is so clear, not just from what happened in Ukraine but we know that the Russian Government was at the side of the Syrian Government in the atrocities that were perpetrated against those who were involved in a civil war in Syria. And so we can have little trust as countries in support of Ukraine that those similar tactics won't be brought to bear against the Ukrainian people.
