I was messing using UE4 on Epic Games Launcher when I ran out of batteries. I put my laptop into charge. When I tried to turn Epic Game Launcher back on it opens and does a sign in thing. Then when it’s logged me in it minimizes the windows on task bar and I can’t maximise the window. When I hover over the window it shows me that there is a home screen but I’m unable to view the window.  
It is also worth mentioning I was downloading something at the time.

I have uninstalled this. I have also modified EGL properties so it’s maximized on start. After doing the logging in phase it shrinks to minimize and doesn’t pop back up when clicked…

Hey halfmoon\_games,

How did you uninstall the Launcher?

Try doing this again through the ‘Remove Programs’ options within Windows. On a Mac you can simply drag the application to the trash bin.

Then navigate to where your ‘VaultCache’ is located for the Epic Games Launcher. You can find the directions for locating this folder on our Launcher Troubleshooting Guide below.

Delete this folder, restart your computer, and do a clean re-install. Hopefully this resolves your issue, but let me know if you are still in need of help.

Thank you,
