Switch this ESC with another one located on the same vehicle to determine if the ESC or the PX4 setup of the ESC is the issue.

It seems like one wire from ESC to motor came loose.

Other (more difficult to fix) causes:

  • broken motor. Actually, the same issue but inside the motor.
  • broken ESC.

As @Omega8 mentioned. Switching motors, ESC, PWM outputs may help to find an issue or failed component.
