Bug Animator going crazy in play mode

Hello everyone, you're my last hope..

So to explain my problem. For an unknowned reason, my unity started to ignore my transition link, triggers, exit time etc.. In play mode.

I made a simple example:

Here is what happend in play mode:

Here is the animator:

Here are my parameters

Here is anomther example:

So, to trigger the Menu In animation you've to press a button that have a trigger on click, same for the out animation. Everything worked few days ago, I didn't touch unity for like 2 days and I don't know how to solve this issue. It's clearly a local bug, because it's working fine on my friends computer (we're working with git)

When I'm cliking out of the play window, it seems to work fine but.. To test my S***, I've to click in this play window so..

I tried to uninstall Unity, delete temp files, switch version, it's remains the same. The fun thing is, when I'm making a build, it's working normaly..

I tryed everything, except buying a new computer but.. well.
Thank you for your time mates..

 

It seem wired for me that a animation stat the has no movement has a length and not just one frame.
2. That the trigger blinking on and of is wired.
Normaly for a state machine that has only tow states i use a bool parameter to define the action. that way its 100 % what the state should be.

 

I tried many things different parameters, the only way for my unity to work is to delete every link between states.. and it's really strange that my preview is F***ed up when on another computer, everything works fine :/
