Hi @cy1990626, welcome to the community!
Can you tell us more about this error? What were you doing when it happened? Can you reproduce it consistently? What version of Cesium for Unreal are you using?
I use cesium-unreal-2.3.0. I don’t know why this is happening, is it something to do with level switching?
I’m not sure, but v2.3.0 is very old. Can you upgrade? The latest is v2.12.0.
