2D Animation will not run after game is built

An annoying problem has come up for me. In the home stretch of making my game, my 2D jump animation (which works fine in the Unity Editor) decides to not work after exporting my game. Literally everything else works after the build except for the jump animation. I’m not sure what I’m doing wrong here, but any kind of help would be greatly appreciated!

EDIT: While the Unity Editor does show it to be working, whenever a scene is reloaded (ex: player dies, game over screen pops up, automatically restarts the level) the jump animation doesn’t work unless I press the jump key twice (meaning a force is added to the player which makes the player jump, but the jumping animation itself is not playing unless I hit the jump button twice). Hopefully this information is helpful to those willing to help me out!

Would probably need to see your jump code, the animator variable you are setting and or maybe a screenshot of your path to jump animation in the animator
