Crash in Hex.Mix.to_lock

elixir: 1.14.1 hex: 2.0.0

Unfortunately I don't remember what I was doing but hex crashed with

Process #PID<0.398.0> raised an exception
** (Protocol.UndefinedError) protocol String.Chars not implemented for %Hex.Solver.Constraints.Range{min: %Version{major: 0, minor: 2, patch: 0}, max: %Version{major: 0, minor: 3, patch: 0, pre: [0]}, include_min: true, include_max: false} of type Hex.Solver.Constraints.Range (a struct).

This is strange as there is an implementation https://github.com/hexpm/hex/blob/50acd48457a726ecc9930099d5dcb324e16efa6c/lib/hex/solver/constraints/range.ex#L431

We have not been able to reproduce this and haven't received any other reports so I am closing it.

A similar issue was recently fixed but it was introduced in Elixir 1.15.0-dev so probably not related. Since it's a missing protocol implementation I am guessing it has something to do with the code path to the consolidated protocols since archives are not consolidated.
