Did you tried to redownload the mod? Looks like there´s something wrong with your local files, as Forge couldn´t load some of the resources of the mod.

Try redownloading and reinstalling the mod and see if it works

That Crash does not indicate that minecolonies is to blame. One of your mods has a wrongly formatted sounds.json file.

As far as I can see however ours is okey. Except for some additionally defined sounds which are not in the jar (the warnings) Minecolonies is not causing this exception.
