Heardle only loading a blank screen

https://kirby-return-to-dreamland-heardle.glitch.me/ only loading a blank screen. I’ve never made one before and know almost nothing about coding so if it’s something in the code I wouldn’t be surprised. It is intended to be an infinite heardle but I’m not sure if it is or what in the code would make it that if it wasn’t, so that would also be appreciated if someone figures it out.
