Cant seem to be able to build lighting

=== Lightmass crashed: ===Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000000

So, this is the whole error. Before this it was about lightmaps so it made sense but this seems like some of the core files have been removed from the system. Am I wrong or is it just broken refs?


This happened while I was working on a environment design. Please, help me out if you have any clue what this error might be in the mean time I will try fixing the issue myself and do some research.
Appreciate your time.
