Yeah they both hated each other, I’m not denying that, but they both wanted to see the downfall of liberalism first and foremost. Then when the Communists were more of a threat, libs and Nazis teamed up. But, when the Nazis became more of a threat, instead of teaming with the libs, they called them social fascists and let country fall to fascism.
Truth is Communism and Fascism are subversive ideologies, they have to destroy liberalism in order for their social order to be successful. If they have to tolerate each other's existence to fight liberalism, they will. This is why leftists didn’t actually care to vote for Harris.
