The rock cycle has to start at least with igneous rocks, some of which will be eruptive.
We may assume that any 'sedimentary' rocks that arrived as meteors have all been metamorphosed, though there are counter instances. For example the Sudbury Meteor and mineral complex. (Canada).

No, the rock cycle does not have to start with igneous rock. The rock cycle is a continuous process that can begin with any type of rock, including sedimentary or metamorphic rock. The rocks can undergo transformation through processes such as weathering, erosion, heat and pressure, and melting, eventually forming new rock types.
