I've been freezing cheese for decades. My mom froze cheese when I was a kid. Your laughing cow should be happy and probably laughing when you let it warm up.
To try it leave one in the freezer over night or maybe even two nights. Then take it out and let it thaw. Taste it. If its ok, then you know there is no harm to letting it freeze and thaw.
Good luck to you and yours.
