please includ the crash report without it I cant help you.

there isn't one, because the launcher doesn't come up

then go into your minecraft folder and get teh crash report from the crashreprot folder. and also get the latest logs in the lgos folder.

Hi there, just want to add that I'm also having this issue with the same exception at GuiFPWorldLoading

I am also running into this. Started after setting the 'tutorialstep' option to 'None' but not sure if that is the cause. My stack trace is identical to the one above.
