Xcode 8 doesn't Start: Loading a plug-in failed
<p>I have a big problem with Xcode 8, can not get it to start ^ _ ^, I always get the following error:</p>

<blockquote>
  <p>Loading a plug-in failed.</p>
  
  <p>The plug-in or one of its prerequisite plug-ins may be missing or
  damaged and may need to be reinstalled.</p>
</blockquote>

<p>I am looking at the logs I could see that the problem is Python, so I tried to update Python, reinstall but nothing very wrong T_T</p>
