Looks like the problem is that we pinned a specific version of ForwardDiff = "= 0.10.12" in the Project.toml, which is no longer compatible with the other packages in Julia v1.11.

I don't remember why I pinned the specific minor versions of some packages but not others... We should see if relaxing these gives the same answers.

Hey Henri! Nice to see you again!!

I think we pinned some versions to fix the output of the model, because different versions of the optimisation packages created different results. Not sure though!
