[UE5 Preview 1] won't build lighting

I ran across another problem in the preview. When I try to build lighting in level I get this error.


I tried delete the swarm cache folder. But that didn’t work. Did someone else come across this problem as well.

is this on Nanite mesh? is Virtual Texture Lightmap support enabled in project settings? My lightmass crashes after completing the bake process.

it doesnt say. it just wont build. And it won’t build for one level.
