Minecraft stops working at load screen.

Ever since I downloaded the new launcher, minecraft crashes and it says that this is the problem.

Local installation of 1.11.2 (C:/Users\colin266\AppData\Roaming\.minecraft\versions\1.11.2\1.11.2.json) has wrong hash; expected 6cf02d45e4e5b190e0e95c7d2df3276ccab2379f but got 12607013aba18a3f2ef5c1810958a8466eb5d4d7
