Black screen when processing light

Hello everyone
Please tell me, I can’t solve the problem.
First: I don’t have any changes in the scene when I add ShperePeflectionCapture.
Second: when processing shadows, the result is just a black screen (SkyLight, Directional Light, BP_SkySphere are added to the scene) and this is the text:
StaticMeshActor_1 Staticmeshactor has NULL StaticMesh property
Map check complete: 0 Error(s), 1 Warning(s), took 0,708ms to complete.
Has anyone encountered this?
Help please.



Try adding a sky atmosphere.

The mesh actor doesn’t really matter, but look for ‘static mesh actor 1’ in the outliner, and delete it.

added SkyAtmosphere. unfortunately didn’t help.

Where is this ground mesh? Is it at 0,0,0? ( recommended ).
