Not able to create this staircase

Have  look at these points here you may need to adjust them so they down overlap and have a 1mm gap between them.  The stair does not like risers lines meeting at a single point

Thanks for suggesting @jay_colcombecolcombe But my staircase design not like that

It was really just to show you it can work with a similar arrangement if you resolve the overlapping riser lines so you are going to need to do some investigation to get your exact solution!
