I set value of character but first time is work fine charter changed but when gameover then if i change the character value will be changed but character still same which i choose first time.

    this.player = this.physics.add.sprite(100, -500, this.charSelect).setOrigin(1, 1);
    this.player.body.setGravityY(1700);
    this.player.setBounce(0.1);

        frameHeight: 92,

    });

    this.load.spritesheet("dude-2", "../src/assets/Character/ch-2.png", {

Answer

You would have to call the function setTexture of the sprite object, to change the texture. here is the link to the documentation, after the reselecting of a new character, or restarting of the game:

 this.player.setTexture(this.charSelect);

Update: As aspected the Error has to do with the animations. Since Animations are based/attached on the game object, not the scene (details in the documentation), you would have to remove the animations before recreating them.

Just add this lines, into the GameScene.js before creating the anims, before the line 93:

    this.anims.remove('left');
    this.anims.remove('right');
    this.anims.remove('turn');
