Hello,
We were unable to reproduce this issue, using Unreal Engine version 5.5.2 (CL: 39378466) and your test project.
[Image Removed]Can you please make sure your graphics drivers are up to date?
If the latest graphics drivers do not solve the issue, can you please share what graphics card and driver version you are using?
Can you please share the logs from the test project where you do not see the Lumen Scene properly populated?
