Second player controller not working when moving maps

I’ve been making a 2d fighting game, and I’ve been making the character select screen. Right now there’s only 2 maps, the character select screen, and the actual fighting game.
When loaded from the actual fighting game both controllers work to control the players, but when going from the character select map to the fighting game map, the second controller stop working.
This is what loads the first character

And this is what loads the second

Any help would be hugely appreciated!
