SceneCaptureComponent2D cant show the captured view in UE5.3

I added a SceneCaptureComponent2D in BP and created a new Render target in texture target. I disable the capture every frame and capture on movement, because I would like to capture it by button. However, it turns out not working in render time.

The error is Scene capture has no viewstate. This may affect virtual shadow map caching performance, consider enabling bAlwaysPersistRenderingState or bCaptureEveryFrame

It gives a white blank photo instead of the real photo of the scene. Can anyone helps?
