What happened?

When I load up the launcher everything is fine but the moment I click on singleplayer it loads for a second but then it doesn't respond and then I have to close the game.

Those errors are very common and i dont see any issues in the log
how long are you waiting before force closing? and how much ram did you give it?

I have waited at least 10 minutes and it stays like that.
The amount of ram I am using is 12000mb
