Can't open epic launcher after windows update

So I recently updated my windows 10 to the latest version (Before which i used to play fortnitebr well), but now when i open epic launcher, a black screen window opens and stays so untill i end the process. Tried all the regular tips, graphics driver are up to date. This is my dxdiag report - link text
I also clean installed this new version and everything once again but that didn’t work either.
Do help!

I have the same exact issue. it all started when my PC did an update to the April 2018 Windows 10 update, now the epic games launcher is failing to open. please tell me if you have resolved your issue!!
