Why does UE crash when I build lighting

Whenever I go to rebuild my lighting, even on the simplest flat planes, UE continues to crash around 34%. I updated my drivers and searched around the forums but now I’m pretty stumped on what causing this. Any help would be great.

Hi sakers288 -

Have you tried to build lighting in the current Preview Release (Preview 4)?

Let me know if the issue has persisted into Preview 4 for you and if you can include the Callstack and Machine ID which appears in the Crash Reporter that would help us narrow the issue down.

Thank You
