Engine crashes on completion of lighthing build


i have the following problem:

Whenever i click on Build->Build Lightning Only the editor crashes.

What i have is:
empty scene, with one blueprint added to it

the blueprint contains a point light, and has Native Parent Class: Light

When i remove the blueprint from the scene the error does not occur.

When i remove the PointLight from the Blueprint (so only empty blueprint with Native Parent Class: Light added to the scene) the problem also occurs.

I really hope someone could help me with that error.

After update to engine version 4.18 it still crashes on rebuild.
