Bike turns on but no throttle response.

I have a 2023 Surron LBX with a cut green wire. Everything is stock and the other day my friend was using it and he said he was riding at full throttle before losing throttle response. I checked all the sensors and the wheel spins freely indicating it’s not a hall sensor issue. What do y’all think the problem could be? Did the controller fail because of exceeding the power threshold, or is it maybe the throttle itself?
