This happens to me. I play side-by-side with my son on an xbox series X. I join the realm and he joins my game. He sometimes gets kicked out due to parent controls and when he rejoins, he spawns at the world spawn with no inventory.
I have found a fix, though!Save and quit and then exit minecraft entirely (click the xbox button on the controller, move cursor to minecraft, then hit the list button on the middle and choose quit. If I reconnect to the realm and he joins my game, he gains his inventory back and spawns in the correct place.
