Morphology

open + up

The meaning 'to make something open or become open' is directly and predictably derived from 'open' (to remove closure) combined with the particle 'up', which here adds a completive/intensive sense. This verb+particle composition is a regular, cross-linguistically common pattern, so a B1 learner who knows the constituent words would reliably infer the MWE's meaning.

Etymology

Open up may come from the image of opening a box or your heart so people can see what is inside; you open the lid and pull it up. That's why it means 'to begin to talk honestly about your thoughts and feelings'.
