It seems that SCIP cannot handle [either nonlinear objectives or nonlinear constraints](https://github.com/scipopt/SCIP.jl?tab=readme-ov-file#mathoptinterface-api). Maybe try replacing it with a different solver (some suggestions given [here](https://discourse.julialang.org/t/alpine-jump-gives-error-for-quadratic-functions/70321/5))?
