"who invaded Ukraine and what were the consequences?"

The Nazi occupation of Soviet Ukraine: The surprise German invasion of the U.S.S.R. began on June 22, 1941. The Soviets, during their hasty retreat, shot their political prisoners and, whenever possible, evacuated personnel, dismantled and removed industrial plants, and conducted a scorched-earth policy—blowing up buildings and installations, destroying crops and food reserves, and flooding mines. Almost four million people were evacuated east of the Urals for the duration of the war. The Germans moved swiftly, however, and by the end of November virtually all of Ukraine was under their control.Initially, the Germans were greeted as liberators by some of the Ukrainian populace. In Galicia especially, there had long been a widespread belief that Germany, as the avowed enemy of Poland and the U.S.S.R., was the Ukrainians’ natural ally for the attainment of their independence. The illusion was quickly shattered. The Germans were accompanied on their entry into Lviv on June 30 by members of OUN-B, who that same day proclaimed the restoration of Ukrainian statehood and the formation of a provisional state administration; within days the organizers of this action were arrested and interned in concentration camps (as were both Bandera and, later, Melnyk). Far from supporting Ukrainian political aspirations, the Nazis in August attached Galicia administratively to Poland, returned Bukovina to Romania, and gave Romania control over the area between the Dniester and Southern Buh rivers as the province of Transnistria, with its capital at Odessa. The remainder was organized as the Reichskommissariat  Ukraine. IN the occupied territories, the Nazis sought to implement their “racial” policies. In the fall of 1941 began the mass killings of Jews that continued through 1944. An estimated 1.5 million Ukrainian Jews perished, and over 800,000 were displaced to the east; at Baby Yar (Ukrainian: Babyn Yar) in Kyiv, nearly 34,000 were killed in just the first two days of massacre in the city. The Nazis were aided at times by auxiliary forces recruited from the local population. (See also Holocaust: The Einsatzgruppen.)
