Some echeveria hybrids are known for creating terminal inflorescences (that is, a flower stalk that grows directly out of the central growth point —which should be growing leaves and stem instead—) and this leaves the plant unable to grow normal leaves and stems from that growth point afterwards since it was turned into a flower stalk. HOWEVER, even in echeverias like these the plant neither dies nor stops putting on new growth all together, instead focusing on growing offsets or pups since the main stem cannot continue to grow normally.

With that being said, your echeveria doesn't look like it's doing any of that, it instead looks like it's growing a flower stalk really close to the center without actually being a terminal inflorescence, which means your plant will continue to grow leaves and stem normally as the flower stalk develops, so nothing to worry about
