Morphology

bob + up

The meaning 'to appear suddenly' is directly derivable from combining 'bob' (a short, quick vertical movement) with 'up' (toward a higher or visible position); the mental image of something moving up into view matches the MWE sense. This motion-verb + particle composition is a common, mostly literal pattern (similar to 'pop up'), so a B1 learner who knows the constituents is likely to infer the meaning.

Etymology

Bob up comes from the simple image of something floating and quickly rising above the water, like a cork that bobs up after being pushed down. So, when a person or problem bobs up, it means it 'appears suddenly or unexpectedly'.
