Hello Ron,
I've seen this problem a couple times in the past, and each time was due to a problem with the size of the floor plan/map.
You want to check the scale of the map, because it is probably less than 1m.
What engineering told me:
Its width and height are both less than 1m (This is most likely a problem
with the scale they set in OneView):
Since the smallest possible map is 1m x 1m (a single cell) this results in
a map with no cells.
If you go in and edit that floor, and set the scale, it should resolve the
crashing.
In both cases, I believe there was one specific floor that was the problem, but it could be multiple floors that are not set.
Let us know if that helps, if not we can look further.
Thanks,
Jason
