Epic Games Launcher Flicker

I downloaded Epic Games Launcher to play fortnite. The instalation went well everything is in place but when I try to open the launcher the launcher window flickers and I can’t do anything. I waited some time to see if this problem is just gonna fix itself but nope. (lol) Anyway when I click on the window itself it stops flickering and it crashes. The CrashReport windows pops up but the window is blank. All white. Can’t do anything. Please help me!
My pc specs (they are enough to play Fortnite on minimum spec requirements)
Processor : Intel Core i5-3337U 1.8 GHz
Ram : 4 GB
System Type : 64-Bit Operating System
Graphics Card(s) : AMD Radeon HD 7670M
(both activated)
Intel HD Graphics 4000
Please help me!

I also have same problem with Intel HD Graphic 4000 and Nvidia GeForce GT 750M
Any Solution Help!!!
