Clients without the mod can't join when opening to LAN

Title. This is relevant to ItemPhysic Lite, though that doesn't need to be installed to repro. Vanilla clients can join fine; only clients with Fabric API but without CreativeCore fail to connect, getting a "Received a registry entry..." message instead.

Sorry but there is nothing I can do about that. The other person has to install CreativeCore as well or you use a dedicated server to host your world.
