Unpack ...0209-natives-windows.jar

Hi, yesterday when I was playing Minecraft, everything as perfectly fine! When I woke up today to play on my mods again, my Minecraft wouldn't launch. It would just say that an unexpected error has occurred. Before it crashed, it said something on the bottom left of the launcher. It said "unpack ...0209-natives-windows.jar" and like I said, my game would unexpectedly crash. In my mods folder, I have 14+ mods, which 2 of them are forge and Optifine
