Sometimes Minecraft crashes and a Message box pops up saying something about a NVidia crash. But the crash message says the error occured in the twitchsdk.dll although I have never streamed and I have disabled all keys to start streaming.
I have not been able to reproduce it, it seems to happen randomly. I have tried to delete all libraries (including the .dlls), but it didn't help. I also tried to reinstall Minecraft completely, this didn't help neither.
Although the twitch libraries are listed as the top dlls, the stack trace indicates your graphics drivers are involved. You may need to update them.
