Scene turns black while meshes don't after baking lights using GPU Lightmass



Hello everyone.

Trying to bake this simple scene with props but at the end doesn’t matter what method I use (GPU Lightmass or traditional Swarm) I get the result which is shown on one of the first picture (second picture shows how the scene looks before baking lighting).

For lighting and reflections in this project I use ray tracing (engine version: 5.0.3).
Every light source is static and post processing volume is set as extended (applied to an entire level).

That’s the tutorial I watched to bake lighting on my scene using GPU Lightmass: https://youtu.be/Tx-PNbKmLPU?si=t8Q0wobXjepGhiJe (and I have the settings set the same as in this video).

What here could possibly go wrong and what can I try to fix this?
This is a problem I must fix because it’s a showcase scene for my props pack and according to official UE Marketplace requirements - lighting must be built on every level.
So I’m really hoping to your help
