Creating Anker instance may be dangerously close to the compute limit

Rebuilding and running again fixed the issue, but it might be that we are dangerously close to the compute limit, and depending on the particular addresses it will fail or pass. If that is the case, then it should be easy to avoid by removing a few of the address print, as formatting tends to use a lot of compute units.
