Its very common on PC see this thread:- TSW3 Early Access Feedback Unreal Engine 4 Crash Reporter Window Appears After I Close The Game.
Ditto: I have been clicking on "save and exit" in the Unreal engine error window every time. Is this worth doing (does the error get automatically submitted?) or must we raise a ticket with DTG?
I don't think DTG get this message from Epic Unreal best bet is to raise a ticket. DTG get to see the magnitude of a problem by the number of tickets raised.
Have you tried waiting before exit? My observation is that the crash might be related to data synchronization with the dovetail live logbook. The logbook logs your runs and mastery progress. If I exit before I can see the update in my profile, I get a crash. If I wait until I see it, I don't.
