After esc calibration the escs just beep and the safety switch doesn't respond too

Hello guys,
I’m using a pixhawk 2.4.8 and I loaded that with px4 1.13.3…after doing the whole setup, my escs would just beep constantly and even after I pressed the safety switch…it won’t stop beeping. I tried arming the drone which works but it doesn’t spin the motors. How should I fix this?

Constant beeping means the ESC is not seeing a valid throttle signal.
