PWM output waveform problem generated by SDK6.4.0

[BY1]

Hello, when I was running the code generated by SDK6.4.0 on STM32G431CBT6, I found that my motor was not working properly. So I grabbed the PWM output generated by Timer 1 and I want to know what caused this

Is your motor sensored or sensorless ? From my experience if you rotate the motor with hand the PWM duty should change
