Whenever I load the unreal engine through the epics games launcher, the ‘initializing’ bar gets to 59% and then freeze, it then crashes with this message:

It ran fine before, however I have updated the engine and now it does not work. I am not trying to load any specific file, just clicking the ‘launch unreal engine 4.7.1’ button in the epic games launcher.
