Game pauses when the idle animation does one full loop

I am making a game with a player doing an idle animation, but the game pauses when the animation does one full loop of the idle animation (the animation is 3-6 seconds long) and it is very annoying. The animation does play, the pausing is the issue, to clear that up.

      if (!Input.anyKey == false)
     {
         isAnimating = true;
     }

This is the script is that is causing the issue. I haven't touched the project settings at all.

I haven't built the project, so I don't know if building it will fix it.
