I don’t see it as a problem per-se, it just defies the notion of having a somehow unique, identifiable self which I understood as a condition for OP’s question and which I suppose is how most people view themselves.
As far as I’m concerned we might very well be just processes that can in theory be copied and recreated. In that case the person in the thought experiment would exist twice at a single point in time and then diverge into to different persons due to different environments and probabilistic processes in the body.
