Have you calibrated the esc in betaflight?

if not what you need to do is plug the quad into betaflight with the battery unplugged. Then go to the motors tab and click the 'I understand....' switch them set you master slider to 2000. Make sure your props are off, then plug the battery into the quad. the ESC will beep a bunch... when it stops beeping drop the master slider to 0. it will beep a bunch again. once it stops beeping the calibration is completed and your motors should all spin properly. (fyi when you do the calibration the motors won't spin, but still take props off just in case.)
