I've applied the *Solidify* modifier of the cup, removed its scale keyframes, applied its scale, recalculated its normals, moved it a bit on +X (so that it falls on the good position) and recreated a keyframe so that it falls correctly, given it an effector *Surface Thickness* of 0.6, then recalculated the simulation (*Cache > Type > Replay*):
