Sorry to hear that. Is it crashing at the same place each time or different? What are your system specs?
Your machine shouldn't have any problems with it and it's strange that you can get that far without any other issues. I would recommend you make sure your drivers are up to date (if they are not already) and install the UE4 prerequisites. You can find them in Cardiac\Engine\Extras\Redist\en-us\UE4PrereqSetup_x64.exe. I used a newly added feature for UE4 called virtual texturing that may be causing issues for some people or may not be entirely stable yet. Unfortunately to remove it I would have to remake every texture in the game and the performance would likely take a heavy hit so it's not something I plan to do at the moment.
