Hey! Happy that it worked out!!
At the beginning I was lost, the log was almost useless, but, after trial and error, I found that the connection was not the issue, like in 5.5.4 and below. The editor was not launching UnrealLightmass, even if I manually launch it, there was no scene imported from UnrealEditor. This leads me to notice that it was not the connection, so, after testing every single version after 5.5.4, none of them work, so the only option left was the change on the editor that broke Lightmass, searching for a bit, I found the following forum: Lightmass CalculatePointShadowing has regression in UE5.6. This gives me the answer, the change of Embree was the error that was happening, I disable it and started working.
