Transparent when using MotionBlur

hello
I have a problem with some objects
when rendering with MB.

without MB everything is correct, when hiding these objects it is also correct with MB,


if they are visible they are not visible in the rendering and there are transparent areas where these objects actually are.

faceorientation,lightpasses,new camera,properties compared

does anyone have something like this

okay the problem is only with rtx rendering!!!
