Xcode 8 doesn't Start: Loading a plug-in faile

Question

I have a big problem with Xcode 8, can not get it to start ^ _ ^, I always get the following error:

Loading a plug-in failed.

The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled.

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

just for the record, Apple says the problem is related to the fact that I updated Python (although I downloaded from the official website python.org) and indicates that 8 of Xcode is more control for the XcodeGhost problem.

I have to try to reinsert the 2.7.10 version and see if this works for me.
