My UEFN crashes on startup 50% of the time. If it does load the output log looks like this.

then when I try and open the project and it crashes it i get this message.

Try going to the Epic Games Launcher \> Library, selecting the three dots on the Unreal Editor for Fortnite, clicking Manage and in the Launch Options write: **-d3d11**

[That’s what worked for me](https://forums.unrealengine.com/t/unable-to-open-uefn-without-it-crashing-on-news-screen-gpu-crash-dump-triggered/1432584/9).

This should be fixed, closing as a duplicate and because of the age of the OP.
