Hi I'm making a grenade that has a SCR_WeaponAttachmentsStorageComponent and AttachmentSlotComponent in order to add/remove a fragmentation case (T168165).
If I try to open the Inspection mode then an error is shown and if you stop the workbench execution it crashes.
That can be tested easily with some rifle, disabling the MuzzleComponent and trying to acces Inspection mode.

As far as i have seen it could be patched adding a verification on SCR_InventoryGearInspectionPointUI line 100

InventoryStorageSlot storageSlot = m_Storage.GetSlot(i);
if(!storageSlot)
    continue;
AttachmentSlotComponent attachment = AttachmentSlotComponent.Cast(storageSlot.GetParentContainer());
