It can take a REALLY long time to generate terrain, just wait for a while.
You can also try clicking "Edit Profile" in the launcher, then check "Launcher Visibility", and change it to "keep launcher open". Then when the game loads up, create the world, popup your launcher, and click "Development Console", and look for "Preparing spawn area: X%"
It's also possible that you enabled lava oceans. they don't work for some reason, it gets stuck at "Loading Terrain". So don't enable dat stuff.
I've been able to generate exactly one world with the Lava Oceans setting, but all of the other ones crash on "Building Terrain." The one world that did generate was tremendously laggy though, so it's quite possible that the option is bugged.
I got this too with one of my customization attempts, and when I restarted the game I couldn't even delete the bugged world, because just selecting it caused it to start loading (and subsequently stall forever/crash the game.) Guess I'll stay away from that lava ocean preset. Although I thought I had enabled it on another world that played normally... must be mistaken.
If you have lava lakes rate below 10, it crashes. This was stated by one of the MC devs
So, basically, if it crashed on you generating a world with few lava lakes, select 11 lava lakes or higher

If you're reading this, then you're definitely not a sandwich.
Sorry, my dear, but I don't give a snickerdoodle.
Spoiler alert!
