What's the major diffrences that we have when we use window instead of skylight on energyplus?

In my project I have several skylights in the roof (about 20), when I try to simulate the model it fail.

If I change the type of constructio from skylight to window it simulate perfectly.

EnergyPlus doesn't have "Skylights", only Fenestration components.

This is merely an OpenStudio object, by default if you draw a window on an horizontal surface it'll be recognize as a Skylight. That allows you in turn to specify a default construction object for those Skylights that is different from the regular Windows.

I suspect your error comes from the fact that you don't have a default Skylight construction defined and therefore after translation to EnergyPlus input file you end up with a FenestrationSurface:Detailed of type Surface TypeWindow that has no construction, and E+ crashes.

On the "Constructions" tab, here showing the default "189.1-2001 - Office" construction set:
