But he didn't explain why the sensor didn't work.
The video released by space agency Roscosmos from the vessel's onboard camera on Thursday shows a steady ascent into space being interrupted by a failed booster separation that sends the vessel into a spin.
The Soyuz is then knocked sharply off its trajectory and can be seen shaking and swinging as the footage is partly obscured by a spewing white cloud.
"It has been proven, fully confirmed that this happened specifically because of this sensor, and that could only have happened during the package's assembly at the Baikonur Cosmodrome."
The Soyuz is now the only rocket that is capable of sending humans to the ISS and a launch failure hasn't happened since 1983. More recently, Russia's space program has been dogged by a string of failed satellite launches involving unmanned vehicles.

Responding to Tuesday's verdict, Japanese Foreign Minister Taro Kono said that the compensation order was "unthinkable". Nippon Steel said it would carefully review the court decision, taking into account the Japanese government's response.
Russian officials believe the component was damaged during assembly.
Smoke rise as the boosters of first stage of the Soyuz-FG rocket with Soyuz MS-10 space ship carrying a new crew to the International Space Station, ISS, separate after the launch at the Russian leased Baikonur cosmodrome, Kazakhstan. During the Soyuz spacecraft's climb to orbit, an anomaly occurred, and the crew was forced to make an emergency landing.
They warned that two other Soyuz rockets could be defective, and said additional checks have been introduced.
Roscosmos officials on Wednesday met with their counterparts from NASA to give them a full briefing of the incident, Roscosmos director general Dmitry Rogozin said on Thursday.
Russian space officials say they hope to resume sending crews to the International Space Station on December 3 after an October launch failed because of a technical malfunction.
Russian Federation is the only country now able to send astronauts to the International Space Station, and the accident caused it to suspend all launches until getting to the bottom of the rare failed manned launch. When the Soyuz launch failed earlier this month, uncertainty over the ISS crew launch schedule led to speculation that the space station would have to be abandoned, at least for the time being.
