Minecraft Is Broken

I finished my giant school world i leave the game and minecraft updates to the new version 1.6.0 and when i join back my ALL my worlds are corrupted i check on the Es File Explorer and i saw 2 Minecraft pictures. I deleted the weird one and it was able to load resources but it won't generate the world i can edit the world or give you the worlds to study but they are all broken
Fix my worlds please!

UPDATE 1:
The World File Is There 😃 it took a full hour to load the world and all i saw was lines and coding all over the place but when i lagged i accendtly broke a block and i heard the block break THE BLOCKS WHERE THERE! but the resources and THE ENTIRE SCREEN was just lines and codes i will send picture if the codes are shown tomorrow so i can reload the world- i am sending a picture i found on my es file explorer from minecraft to show i'm not lying but to say it looks s amazing! On the Es File Explorer the white was black and the grey was white
Update 2: It Was my shaders pack the update broke.... So i just wasted my time...
