Why does this crash occur?

I have installed the engine along with the epic launcher, I downloaded the Game file of Fortnight and tried to open once it is installed. At the first time it opens. But later on it crashes.

I have tried uninstalling and reinstalling it once again but still it doesnt work.

Please help me with the issue
