Bug Player animation stops working on profiler build

Hi, I'm not sure if this is the right place for this question, but my player animates just fine when I'm testing the game on editor (classic 4-directon top down movement with pixel sprites, nothing complex), but anytime I create a profiler build it suddenly stops animating (you can move the player, it just doesn't show any walking animation). Then, when I go back to the editor, the same thing happens until I restart Unity, and it goes back to working fine while on editor. Why could this be happening?
