UE4 4.15 Crashing when build lighting

I have an environment that I’m trying to build lighting in. I’ve built the lighting in this environment many times in the past without issue, in 4.15. However now my editor consistently crashes every time I do it, and doesn’t even generate a crash report at that. The editor just closes. Has anyone else experienced this in 4.15? Or at all?

If your editor is crashing and closing without producing a crash reporter window try using Windows Event Viewer to see why Windows is causing the crash. You can follow the information in this Wiki I set up a while back. It will help you find the error code for Windows and then you can Google and investigate why it’s happening.

In my experience with most of these issues, it’s not usually reproducible on our end and comes down to the end-user resolving an issue with their own system. It may be helpful to post an AnswerHub with the details of the crash and the Windows Event log to get further help from our Support staff, though.
