I have a light in my scene which was originally a Stationary Light and it worked fine. enter image description here

I wanted to change it to a static light to optimize performance, but after changing it and building the lights, the scene turned dark. enter image description here

I have confirmed that the objects here are of a static type, but I am not sure what the problem is and I'm seeking assistance.

Did you enable Lumen? It's default for UE5 is on. Lumen will disable static lightning. See the documentation of Lumen: When Lumen is enabled for a project, precomputed static lighting contributions are disabled and all lightmaps are hidden. https://docs.unrealengine.com/5.0/en-US/lumen-global-illumination-and-reflections-in-unreal-engine/

YES! Thanks Bro. So should I disable the option "allow static lighting" in the project settings when Lumen is enable?
You can't use static lightning or baked lightning in combination with Lumen global illumination. You have to decide wether you want to use Lumen or not.
