Illumination error with gpu lightmass

Good day, i have a problem when i use gpu lightmass official in Unreal 4.27.1, When I finish building my stage with the default options you can see some white spots on the meshes, try to increase the quality in the settings, but unreal engine crashes, the equipment I use has I5-7700, RTX 3060, 16 ram 2666mhz, I would appreciate any help, have a nice day.

Hi!

I think your light is intersecting a mesh!
…or maybe you use boost somewhere (like indirect lighting intensity under your light settings, or diffuse boost under lightmass…)
