a JNI error has occurred, please check your installation and try again and A java exception has ocurred error after exporting the program in eclipse

After exporting the program, when I try to run the JAR file, the error occurs: a JNI error occurred, check your installation and try again followed by a java exception occurred. I have no idea how to solve this, I don't know if it's something about the code or the Java version I'll post the code here (the main code) so please help!

My java is: 8 281 as JDK

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;

import javax.swing.JFrame;

public class Game extends Canvas implements Runnable, KeyListener{

    /**

    private static final long serialVersionUID = 1L;
    public static int WIDTH = 160;

    public Game() {
        
        this.setPreferredSize(new Dimension(WIDTH*SCALE,HEIGHT*SCALE));
        this.addKeyListener(this);
        player = new Player(60, HEIGHT-5);
        enemy = new Enemy(60, 0);
        ball = new Ball(60, HEIGHT/2 - 1);
    }
