Unreal crashes during encoding textures after light build

I am trying to rebuild the lighting for the simple starter level. Currently i have only being writing the c++ and blueprint aspect of the game have not gone into designing levels, lighting etc, at all so im not sure why this has triggered. I am currently knee deep in understanding and writing a better ai system so i do not want to lose focus on that task to address this one. Any help will be appreciated.

I have the same issue. Have found a solution?

no this site doesnt really answer questions do they?

any solution ?

i believe i had two sky spheres in the scene or something. i do not know how that happened lol.
