Whenever I try to launch Minecraft, the Mojang screen hangs for a bit and then it crashes. The crash message says this:
The game crashed whilst initializing game
The game crashed whilst initializing game
Error: ddj: Unable to fit: minecraft:block/lava_flow - size: 32x32 - Maybe try a lowerresolution resourcepack?

This is the crash report I get:
