I use Vue and cesium to create an app, which is rendered normally when I open it for the first time; However, switching routes will result in a rendering error.

I realized that the problem might be caused by this function.When I annotate this function, Everything is back to normal.

async function loadModel() {
    const airplaneUri = await Cesium.IonResource.fromAssetId(545921);
    const airplaneEntity = viewer.entities.add({
        availability: new Cesium.TimeIntervalCollection([new Cesium.TimeInterval({ start: start, stop: stop })]),
        position: positionProperty,
        model: { uri: airplaneUri, minimumPixelSize: 128, },
        orientation: new Cesium.VelocityOrientationProperty(positionProperty),
        path: new Cesium.PathGraphics({ width: 1 }),
    });
    viewer.trackedEntity = airplaneEntity;
}
loadModel();

This is the call stack of the problem
