UE5.5: Lyra's default mesh won't effect by SetOwnerNOSee

As the title saied, If I set the Mesh(CharacteMesh0) in B_Gero_ShooterMannequin SetOwnerNoSee, I can still see the lyra model (B_Manny), but if I change the B_Manny’s Skeletal Mesh Asset from SKM_Manny to SK_MannyQuin, the model will act normally. I think it should be the SKM_Manny’s problem but I don’t know what kind of problem it has.

Does anyone know about this?

Fixed, It’s caused by Nanite support of default mesh
