Rendering stops when an error occurs, how can I start rendering again?

When a renderError occurs, viewer.useDefaultRenderLoop is false.  
[https://cesium.com/learn/cesiumjs/ref-doc/Viewer.html#useDefaultRenderLoop](https://cesium.com/learn/cesiumjs/ref-doc/Viewer.html#useDefaultRenderLoop)  
Rendering should resume by setting viewer.useDefaultRenderLoop to true.
