Yes, the KPD and the NSDAP both rejected parliamentary democracy and briefly formed a blocking minority in the Weimar Republic. Nevertheless, I do not think it is correct to speak of the KPD enabling or supporting the NSDAP’s seizure of power - on the contrary. As I said, the situation is quite different with the conservative forces of the time - they were definitely at least partly to blame for Hitler’s rise.
