Black Tiled Sky Sphere in UE5

Hi, I’m new to unreal and I was setting up a day/night cycle. I got it to work and look fine but I eventually messed something up and now it’s stuck on this weird black sphere. Even if I migrate a working bp from a different project as soon as I open it, it immediately goes black.
