Objective function is sigma(max (0, C_i[i] - d_i[i]))

I use cp_sat from ortools.sat.python to solve a constraint programming problem. However, my Python interpreter just stops in the middle of a solve, without printing a stacktrace.

I have this function to find the best route:

I ran the official code that Google has in its documentation.

I have been going through the online documentation and the samples available on Github, but I was not able to find an example on how to provide an initial solution (or warm start, or solution hint, depending on the preferred synonym) to a compatible MILP solver when modelling through OrTools mathopt in Python.
