if anyone face this on the future, i manage to fix the problem by debugging for some hours following this great guys steps :

{GameDev} : How to Handle Infinite Loops in Unity.

anyway the cause was cinemachine dolly track specially CinemaMachineSmoothPath Script, i was using one waypoint as default value for waypoints, because i didn’t need to specify more
i have a script was assigning them on the runtime.
So the editor was looping for no reason before clicking on the play button causing it to freeze like above.

@Gregoryl i know it’s my mistake for not assigning more than one waypoint but if you can request to add some safety that doesn’t allow to specify only one waypoint on the editor you would save hundreds of lazy dudes who hate to work in weekend to debug things.
