Lighting Bug after join Battle Royale and returning to any UEFN/Other Experience AFTER V43.00

Summary

If you enter a map immediately after launching Fortnite, the lighting works correctly. However, after entering a Battle Royale match and then returning to any map or experience (including other Epic Games experiences such as Fortnite OG), the lighting becomes bugged.

The issue mainly affects Exponential Height Fog, which appears to no longer functioning correctly.

The issue persists across different maps and experiences, not just a specific UEFN island.

WORKAROUND:
The only way to fix the issue is to completely restart Fortnite and enter a UEFN map immediately, before entering any Battle Royale match. The lighting then works correctly until the issue is triggered again(Join Battle Royale)

Would like to add that the lack of fog is happening both in editor and ingame for me - even without entering br before hand. Fog seems to dissapear when using the day sequence device, this causes a multitude of visual issues

I have sent this to reviewed by the team too

thank you!
