Menachem shmei, absolutely Hashem doesn’t have partners in running the universe. Hashem created the world in a specific way that humans are the vehicles in the creation of other human beings, hence parents are called partners in the creation of their children, but do they actually create their children? Absolutely not. Humans can only be parents if Hashem wills it to be so, from the starting point until the finish, parents do not create their children, they are vehicles, and hence called partners, in the creation of their children.
This is the danger of Chabadianity. Just like Christianity, they mistranslate or misinterpret and take out of context a posuk in Tanach, Orin Chabad’s case, a Gemarah or another source, and that they warp into supporting their getchke.
