Problem - Lightigs needs to be rebuilt! - Please help me

Hello there! I’m trying to modify the map, and I can’t fix the error after making changes: Lighting needs to be rebuilt…

I tried to click Build All, but it didn’t lead to anything. The lighting broke completely…

please Help me, I’m tired of fighting and looking for a solution to the problem
