Actually, it's no problem at all for evolutionary theory. Abiogenesis refers to a multitude of hypothetical models of how life could arise from chemical precursors.
Evolutionary theory describes the descent with modification of species.
Evolution depends largely on the idea of natural selection. But natural selection requires that the species are able to reproduce, and so that means that the first living organisms from which all others are descended must have had the ability to reproduce already. They could not have evolved the ability to reproduce. It's possible that the reproductive system could have evolved to be more complex and fail-safe, but we need to explain how the first reproductive system started. That we do.
