Welded Parts Being Deleted Off Tool In VR

I’m trying to make a pistol script and I welded it together so it wouldn’t fall apart and the items are just deleting sometimes it works but when it works i boot up the real game and it just falls apart here the hierarchy I don’t know what this could be. I’m using the welding plugin to weld these. It works whenever I am on screen but when im in vr it disappears but the muzzle flash still works i would see the green box where it is but it isnt and the gun mesh isn’t there either.
