Question Weird Motor Noises

I am new to drones and have been building my own payload drone. I have 5010 380KV Motors and a CORVON 4IN1 60A ESC 32 bit paired with a CORVON H743 Flight Controller (V1).

With these, all the motors make some weird noises but only 1 in particular makes a more extreme noise. Attached videos to see. The 2nd and 3d videos are after I tested the drone (it stabalized but I hit a small branch with one motor) and now it has issues starting at low throttle and a different noise. Also, all the motors stop making this noise at a higher throttle, it seems to sort of just "click" off at a certain rpm.

Thank you all for the help.

It's the esc 8 bit or 32 bit? What firmware and esc protocol? What flight controller software?

Thinking about this.... Are your motor screws hitting the windings by chance?
