LibGDX Project crashes only after restarting

Sometimes, about once in 20 attempts, the game crashed.

It doesn't make sense to me. After the first start I tried to reproduce the error about 500 times. But without success. After restarting the game, the game crashed after the 12th attempt. This only affects Windows. I could not reproduce the error on 2 different Android phones even after approx. 500 attempts.

I've been looking for similar errors for over 8 hours, but they didn't come close to my Problem and didn't help me.

I have System.out.print instructions everywhere and found after 1h that the game crashes due to the following line: body = world.createBody(bdef);

I tried all the proposed solutions, added security if Statements everywhere and tried every conceivable suggestion from the Internet (what you can see in the code below) Nothing helped.

public class Coins extends SpawnAble {

    private TextureRegion textureRegion[][];
    private Texture texture;
    private int framecount = 0;
    private int frame = 0;
    private int startcount;

    public Coins(Playscreen playscreen, float x, float y) {
        super(playscreen, x, y);

        texture = new Texture("spr_coin_strip4.png");
        textureRegion = TextureRegion.split(texture, 16, 16);

        setRegion(textureRegion[0][frame]);
        startcount = (int) (y * 100) / 16 * 10 - 64;
        System.out.println(startcount);
    }

    @Override
    public void defineSpawnAble() {
        BodyDef bdef = new BodyDef();
        bdef.type = BodyDef.BodyType.KinematicBody;
        System.out.println("Body Created Kinematic");
        bdef.position.set(getX() + getWidth() / 2, getY() + getHeight() / 2);
        System.out.println("set position "+world.isLocked());
        if (body == null) {
            body = world.createBody(bdef);
        }
        System.out.println("set crated");

        FixtureDef fdef = new FixtureDef();
        CircleShape shape = new CircleShape();
        shape.setRadius(6 / Statics.PPM);
        fdef.isSensor = true;
        fdef.shape = shape;
        fdef.filter.categoryBits = BIT_FILTER.SPAWNABLE_BIT;
        fdef.filter.maskBits = BIT_FILTER.PLAYER_BIT | BIT_FILTER.BRICK_BIT | BIT_FILTER.DEFAULT_BIT | BIT_FILTER.OBJEKT_BIT | BIT_FILTER.MOVING_BIT;
        body.createFixture(fdef).setUserData(this);
        System.out.println("set userdata");
    }

            if (!toDestroyed && !destroyed) {
                framecount++;
                if ((framecount % 15) == 0) {
                    frame++;
                    if (frame > 3) {

                    }
                }
            }

I am very grateful for any kind of idea.

I solved the problem by myself. If you have this Problem, dont try to change jre version. Libgdx need 1.8.

If you have this problem, I'm really sorry, this problem can have many reasons. I have listed a few here:

• Bodys are created multiple times (world.createBody) or destroyed multiple times (world.destroyBody ())
• You create or delete a Body as the world progresses (world.step)

In my case, I disposed an object incorrectly.
