[MC-3928] When I enter singleplayer it sens me back to the title screen.

I had alreadty had minecraft 1.4.5 for a few days, and one afternoon, I was logging into one of my creative singleplayer worlds. I got stuck on the screen that said "Chunks loading" or something like that. Then it sent me back to the title screen.

I had mods, so I force updated minecraft, but that didn't help.

When I was stuck on the title screen I waited a few minutes and minecraft crashed.
I attached the crash report.

Steps to Reproduce:
I don't know how to reproduce it, I can't NOT reprodce it

what do you mean by downgrade?

downgrade to a earlier version of minecraft it's worth a try

or you could try deleting everything in your .minecraft (but you saves texture packs etc.)

and is your world corrupt

You should consider updating your java as your version is outdated.
