My friend was also having this issue what fixed it was changing his Minecraft Path in the twitch launcher he moved it to his other drive. The only difference between his installation and mine was the fact that his windows username had a space in it ie: C:/users/John Smith/ but mine for example is C:/users/johns/ Spaces in the file path could be a issue for users using windows if the launcher is doing something to the file path before it reads from the disk. This may be a red herring but try changing your minecraft path in twitch launcher to a different path without spaces.
