[SOLVED] Problem with animation after building for Windows

Hi,

I'm making an app that is working fine while I'm playing it inside Unity. All animations, buttons, and everything work fine in Unity. However, when I made the build, the animations suddenly stopped working. The animations with problems are triggered by clicking a button. I've made a test playing animations without any trigger and it worked. So, the problem happens when clicking is involved.

I've tried all the solutions for similar problems that I saw in this (and other) forums: 1) restart Unity, 2) close and reopen the Animator tab; 3) make another Animator and other animations. Nothing worked.

I've implemented a Debugger in my build and this is what it returns when I click the button that should play the animation. Anybody can help me, please?

SOLVED: The button I'm using to play the animations had a 'missing object' OnClick() via inspector. When running it through Unity the problem was ignored, but it crashed when built.
