Russia's Space Agency, Roscosmos, has been thoroughly investigating the botched launch of a mission to the ISS. According to a press release, a damaged sensor pin led to an "abnormal" separation of one of the boosters. Up until recently, the ancient Soyuz launch system was notoriously reliable, which is why it's the only system capable of lobbing astronauts up to the ISS now. Fortunately, Roscosmos seem to have a lid on the issue, and have another manned launch scheduled for December 3, 2018, with a return trip on December 20.
Check out more footage of the launch here.
As follows from the findings of the Investigation Committee told to reporters by Oleg Skorobogatov,"The launch ended up with a launcher failure caused by abnormal separation of one of the strap-on boosters (Block D) that hit with its nose the core stage (Block A) in the fuel tank area. It resulted in its decompression and, as consequence, the space rocket lost its attitude control." The abnormal separation was caused by the non-opening of the lid of the nozzle intended to separate aside Block D oxidizer tank due to the deformation of the separation sensor pin (bended by 6˚45‘) . It was damaged during the assembling of the strap-on boosters with the core stage (the Packet) at the Baikonur Cosmodrome. The LV failure cause is of the operational nature and spreads to the stock of already assembled packets of the Soyuz rocket.
