Morphology

muddy + up

The verb 'muddy' already means to obscure or confuse, and the particle 'up' here functions as an intensifier/completive, so 'muddy up' straightforwardly means to make something more unclear or complicated. This compositional pattern (verb + up = increase/intensify the verb's action) is common and cross-linguistically familiar, so a B1 learner who knows both constituents can reliably infer the meaning.

Etymology

Muddy up comes from the image of stirring mud into water so the water turns cloudy and you cannot see clearly. That's why people use muddy up to mean 'to make something less clear or more confused'.
