after add slot Model is infeasible

How to arrange the same task to start at the same time? – Gurobi Help Center

After I've added the slot to the calendar, when I try to add it to the constrain it turns out that the result is infeasible, which I'm not sure where I went wrong.

I've tried integrating the time slot into the calendar, but it doesn't work. Since there will be a problem that constrains gapworktime since it has dairy requirment which makes schedule inconsistency. Which now I still can't find a solution. If you can help that would be great.
