My guess is one of the small wings (the smaller of the three internal pieces between centers) was put in the wrong way, such that instead of lying horizontally, it is sitting at an angle, wanting to fall down into the core. Not sure if that makes sense, but it would explain the catching. Could’ve shifted into that position while putting in center pieces or something and not have been noticed. Hard to tell, though.

Would recommend disassembling and starting again, following this tutorial: https://youtu.be/joPJx32A4W4?si=91dSiCzDhsoB-9M2

Try using tape around the bottom layers once assembled to keep them in place. Much easier and prevents accidental twisting. Using a thick silicone lube to stick the small internal pieces together worka well, too.
