Inventory works in viewport but not standalone

I am not sure if its a bug or what, but i have an inventory that shows items on a grid when I pick it them up. It works on viewport but not standalone. This is the code i have:

Inventory:

Inventory Slot:

Player:

Can anybody please shed some light into why the items would show up on viewport but not standalone? I’ve done print strings and it stops at the inventory code. I’ve done some research and I tried to see if its an unreal thing or if its me but no kind of real luck…
