chronyd and ntpd both use UDP port 123, so each will terminate the other 
when it starts.  If both are enabled, chronyd's unit file indicates that 
it should start after ntpd, so it will always "win."

You probably have both enabled, so the system boots, starts ntpd, then 
starts chronyd which terminates ntpd.

Disable chronyd.
