It's not a good argument. Both Russia and Ukraine are important wheat producers - without them the world may experience shortages, this is a direct result of the invasion and nothing to do with covid. Same goes for the current shipping crisis, it's caused directly by the economic effect of sanctions and the backlash felt on the supply chains. Maybe those problems were created by covid to some extent, but they were being ironed out already and some restrictions are being lifted right this moment. But the war exacerbated all of those problems.
