// Create Camera

const width = this.container.clientWidth;

const height = this.container.clientHeight;

const aspect = width / height;

const viewSize = 10;

this.camera = new OrthographicCamera(-viewSize \* aspect, viewSize \* aspect, viewSize, -viewSize, 0.1, 1000);

this.camera.position.set(5, 5, 5);

this.camera.lookAt(0, 0, 0);

Try change near, far:
this.camera = new OrthographicCamera(-viewSize \* aspect, viewSize \* aspect, viewSize, -viewSize, 0.01, 100);
