Missing sound packs in song

So I no longer have access to my old iPhone on which I made most of my GarageBand projects but transferred them through iCloud.

However when I try to open them I get the error “Missing Sound: This song is missing sound packs that were originally downloaded from the GarageBand Sound Library.”

Even after downloading every sound pack in garageband this error still shows making me think it might’ve been something in sampler etc that I have no way of ever remembering. Does anyone have a solution/any advice? Desperate for some help, made this account just to ask as all my ideas and rough sketches are saved there. Thanks.
