Lightning Build gives problems

Hi UE Folks,
For the last couple of days, when I try to build the lights, I get the error MapCheck: Error: WorldSettings_1 Maps need lighting rebuilt. I read all the possible solutions and none of them worked. The problem is that it happens to me even when I open a new fresh project. I reinstalled UE, XCODE, the situation did not improve. The operating system is MAC OS Ventura. below you have a copy of the logs from the fresh project, so I just create a new project and try to build lightning, of cours light build never pass 0%.
Thank you for your help.
