There is an 8-way thread on the helicoid. Make marks on the parts and try to screw in different positions. The correct position is when, when screwing in, the marks of infinity and control risk coincide. But, obviously, they disassembled your lens and did not put two parts that prevent complete loosening. In this video, this detail can be seen at 10.34 on the lower right inside the case.

P.S. I will add. You may need to remove the rear flange (by unscrewing three screws) to align the jumper arm and the diaphragm control stem. But be careful, there are small balls under the diaphragm ring and it is better not to touch the ring itself.

But with such a defect it is probably more correct to return the lens to the seller.
