Well, it has a kernel of truth.

But yeah, the nazis were funded by Kremlin. Because of losing their main source of income in most of Ukraine, after 2014 the prevalence of far-right extremist attacks has decreased everywhere in the rest of Ukraine, but risen in Crimea and the occupied Donbas. In 2014 Ukraine’s armed forces were a joke, because they figured nobody will ever attack Ukraine and even if someone does, the Russia will come for help. Therefore, the main function of their armed forces was to be free workforce for the highest officers. Almost no useful training in use of weapons took place. The only people who really understood something about fighting were the Russia-funded nazis. And, being nationalists, they then refused to allow the Russia to take over Ukraine in 2014. After that, Ukraine began a sllloooowww process of dismantling the nazi organizations, which was extremely dangerous, because those organizations were stronger than Ukraine’s armed forces and were dreaming of taking over Kyiv. But, by around 2018 all of those units had been integrated into Ukraine’s armed forces and watered down so that new recruits could join them without having to encounter nazism.

Ukraine has done an extremely good job neutering the nazi organizations implanted there by the Russia. It’s beem a huge error by the western press that this process was not written about between 2014 and 2022. There were articles about it – at least in Finland – around year 2005 when Putin originally started funding nazis in countries tied to the Russia, but after that… Nothing.
It’s true that the Russia was stopped by its own nazis in 2014, but it’s untrue that those nazis were connected to Ukraine’s government.
