      So the point is, that Minecraft is instantly crashing in the new snapshot 17w50a
      Btw: im using a mac os with java Installed, if that is helpful.

      The game crashed whilst initializing game
      Error: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Unterminated object at line 4 column 28 path $.pack.description

      If im clicking on the show crash report nothing happens...

      But in the output log it says following:

      18:42:29 vf Client thread error Something went wrong upgrading!
