Unreal engine 4.8.0 will not load past 35%

I installed unreal 4.8.0 and when I tried to run it. It just loaded up to 35% and has not loaded past that for 30 min.
i have tried to uninstall and reinstall it.

does anyone know how to fix this?

I’ve faced same issue at preview version, turns out this wasn’t lag but shaders was compiling a background. Check your task manager, maybe its a same and you just need to wait more.

just a guess

after another 20 - 30 min it crashes

it just crash after a while.
