You may need to reinstall the locally installed files that Minecraft puts into place.
To do so, press your Windows+R keys, type in %AppData% at the dialog, and press Enter. In the window that appears, open the .minecraft directory, and delete everything except for the saves directory that you see therein. Then, try running Minecraft again. Good luck!

The error:
The game crashed whilst updating screen events
Error: java.lang.NoClassDefFoundError: io/netty/channel/local/LocalServerChannel
I can't access the crash report for some reason
