Lightmass fails build when precomputed visibility is enabled

When I enable precomputed visibility in the world settings swarm gives me this error (Exit code: -1066598274) and then stops the build. My work PC has 16 GB ram and an 17-6700 CPU @ 3.40GHz

Any idea what could be causing it?

How do you setup pvs?

Do you have pvs volumes in map?

Is this volumes placed only in walkable area?

Which generation method you use?
