Epic Games Launcher keeps crashing and Gives me a gray tab

Every time I try to open the Epic Games Launcher, it crashes and gives me a gray tab which I found out was supposed to be the unreal engine crash report. After about 20 seconds the tab disappears and nothing happens. I have allready contacted Epic Games before and they told me to download a new driver but, after having done that, still nothing seems to work. How can I fix this?

I also have this problem please help!

I fixed problem by uninstalling epic games launcher and installing it again and I also used repair option to fix unreal engine!
