Re: Constant crash: Unreal Engine is exiting due to D3D device being lost.

Just ran into this problem today after everything working just fine after launch.  The only thing that changed was that I updated to the latest nVidia drivers (released on 11/26/19).  I would basically be able to launch the game, but as soon as I got to the mail title screen with menu options the video would start flickering for maybe about 5-10 seconds and then the signal between my card and monitor would be lost and the monitor would start cycling through inputs until finally giving up. 

I changed the following which seems to have fixed it.  I had to change the settings in the nVidia experience application, but here's what I changed:

Old value:  2560x1080

New value:  3440x1440 (this is my native resolution)

Old value:  Full Screen

New value:  Full-Screen Borderless

I think the game had problems switching to full screen and that's what caused the issue, but not 100% sure.  So, might or might not fix other issues but thought I would share what worked for me.
