I updated to 0.4.11 and the game just won't start. I had the same issue when the version 0.4.10 came out so I just waited for the next version maybe it will get fixed, but unfortunately it still crashed. Version 0.4.9 runs just fine.

let me guess u using Optifine?, ATm team added twilight forest in ver 0.4.10 and somehow but optifine is not friendly with twilight forest, delete twilight or optifine to play on latest versions.

Yeah, removing optifine solved it. Thank you
