This is due to an error on our side to properly clear out old GI cache data when updating the lighting system. This causes the system to attempt to load data that is no longer valid. The solution to this is to clear the GI cache: Edit->Preferences->GI Cache->Clean Cache. This has been fixed in 5.4+.
