Double check that gear mesh at the spur/pinion!!!! Because when you released the throttle, I think I hear a buzz.
The video sound is not conclusive enough however.

Hard to tell by the video, but check the pinion and gear mesh. Something could of come loose! ?‍

User Error. When you installed the motor/ pinion/ spur on this EXB roller. Mesh seems too tight. A common mistake.

Only you can check and know for sure.
