I am in 4.26 non preview release version…Lightmass CPU build crashes at the building texture streaming part. It doesnt do this for a brand new level, but all of my old levels so far it does this for… Even when i use just one of hteir sub levels alone…
What can i do to fix it?

EDIT
I actually found out if i build → texture streaming… and have any material with some tesselation set up… then it crashes… moment i remove the meshes with tesselation it builds fine. So what do i do about that???
