Rendering in Movie Render Queue cesium terrain apears at the end

Hi, can anybody help me with this rendering problem. When rendering animation in Sequencer Cesium terrain apears only in few last frames. This never happened to me before so I am wondering is there a quick solution for this problem. I am using UE 5.11 and Cesium is updated also. Thank you

I’m not sure what might cause that. Can you reproduce the problem with a simpler sequence or in the Cesium for Unreal Samples project? Can you share a video of what it looks like?
