cant load game

when clicking the play button in the launcher (for all versions)
it gets to the mojang screen then crashes giving me this message "The game crashed whilst initializing game
The game crashed whilst initializing game
Error: byx: Unable to fit: minecraft:blocks/lava_flow - size: 32x32 - Maybe try a lowerresolution resourcepack?"
i have completly uninstalled and reinstalled minecraft and java to try and fix this but it does not.
