As I mentioned before, unless I have a way of reproducing this crash on my end there is not much to report.
I did open the logs for the most recent crash you are getting and noticed your drivers for you 980 TI were a little out of date. Currently the most stable drivers for that series of cards is 372.90 Released 9/21/2016.
Is this a VR project, and do you have the HMD connected while you are attempting to open the project map?
Thanks,
