@kevin3 can you share the files involved in that crash and describe the steps to reproduce it?
@archist97 we have fixed all crashes and bugs related to worksessions reported by users (except this overhead display issue you reported here: GH Style 2D Representation on Plan View). If you are still experiencing bugs related to workessions with VisualARQ 2.12.4 please let us know, so that way we can fix them.
