Why is my game not switching scenes?

So i built this game with a character selection menu, the menu is in a seperate scene and when you press select it switches to the game scene with the character that you chose, and it works totally fine in unity but when i built it and uploaded it to itch.io the select button doesn’t press and the game doesn’t switch scenes, why is this happening?

when you build you game make sure you selected all scenes else they won’t be built
