I am developing route optimiser using timefold python but ArrivalTimeUpdatingVariableListener is not running I also included print statement to check if it’s running in background or not. I have used the code that was given in the tests folder in timefold_solver_python official repo.

I am trying to port an OptaPy Problem to Timefold/Python.
