In my experience as a tutor, the primary reason calculus is so difficult is that it is sitting atop an upside-down pyramid of previous math concepts. Those are the obvious reasons why calculus is hard. The problems are often longer and more involved, sometimes taking a full page or more of written work to complete.

You have to wrestle with new vocabulary, new symbols, and new processes. Calculus asks you to think in ways that are more abstract, requiring more imagination.

The concepts take you far beyond the comfortable realms of algebra and geometry that you’ve explored in previous courses. Calculus is widely regarded as a very hard math class, and with good reason.
