Tried reading over the crash report myself but I can't understand it anyways. The last thing I did before I got this problem was I had loaded the world but was tabbed out and it sat at the in-game menu for a few minutes, then I accidentally closed Minecraft. Tried to load it later and it just sits at "Loading world" but the console says that the world unloaded and saved.
