This post is a great starting point for debugging issues like this: [PSA: How to help yourself debug differential equation solving issues](https://discourse.julialang.org/t/psa-how-to-help-yourself-debug-differential-equation-solving-issues/62489)

The documentation suggests `BS3` may be close to `dde23`: [DDE Solvers · DifferentialEquations.jl](https://diffeq.sciml.ai/stable/solvers/dde_solve/#Nonstiff-DDEs)
