Morphology
crack + up
The meaning 'to suffer a mental or emotional breakdown' is directly built from 'crack' (to give way emotionally) with the particle 'up' providing a predictable resultative/completive nuance. This verb+particle pattern is common and the core meaning is present in the verb, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
Crack up comes from the image of a person laughing so hard they seem to crack or burst with sound. The verb crack means 'to break' and with up it shows a sudden move into laughter, so the phrase means 'to laugh loudly'.
