I think you need to do some more investigating. The core cause of this conflict is and always has been NATO and the West.

The entire point of NATO was to counter the USSR and deprive other nations of the freedom to choose their own economic system and force their own (capitalism). When the USSR fell, instead of dissolving as they'd lost their purpose, they continued to expand (and this was after they had promised not to) eastward, eventually threatening to reach Russia's borders.

You see, the West has always wanted to punish Russia for their 1917 Revolution, by breaking up the country and dividing it up amongst themselves like they did with the Middle East (which also is partially why there's conflict in Palestine right now), so of course when their biggest threat to their capitalist world order collapsed they wanted to ensure it's destruction.

You can Google the rest. The Euromaidan coup, Odessa massacre, Azov Battalion, Stepan Bandera, Minsk Agreements (both Germany and France had admitted that they were there to help Ukraine build their army), there's a lot of information about this that goes beyond "Russia attacked poor Ukraine in 2022 for no reason".
