Fractured mesh artifact when Path Tracing render

hi I have an issue when I render a fractured geometry collection in path tracing
(In deferred there’s no problem)

When converting a mesh to a Geometry Collection in Fracture Mode, shadow artifacts appear (the issue often arises immediately upon conversion to Geometry Collection).
This problem only occurs in Path Tracing (Deferred works fine).
In some objects, only certain internal faces have the problem.
The issue occurs even when I test with common cube.

What I’ve Tried:

It’s not a UV issue, and changing materials doesn’t resolve it.
Adjusting nearly every parameter, such as the Dynamic Shadow Distance of the Directional Light, hasn’t resolved it.
I’ve tried various Project Settings, such as setting GI to None or changing Virtual Shadow Map settings, but the issue remains.
I’ve also tried entering r.RayTracing.Nanite.Mode 1.
