Unity UI not working in Editor after porting from Unity 5.0 to Unity 5.1 (have to restart Unity to work)

I am having a really strange issue after porting to Unity 5.1 from Unity 5.0

When playing the game in the editor, everything works just fine the first time. Then, after stopping the editor, anytime I play the editor none of the UI is responding. I get no errors and no new warnings. If I restart Unity then, it will again work for only one time, then the UI is broken again. This mean I currently have to restart Unity everytime I need to test, which is clearly unacceptable.

If anyone has any clues about what could be the issue, I’d appreciate it. Thank you.

Some additionnal informations :

  • The build for mobile works well.
  • I’m using Facebook API and SOOMLA.

Alright, I think I found a fix. Simply reinstalling Unity didn’t work but a clean install did. I uninstalled then reinstalled 5.1 and it seems to work now.
