Is your Mac starting up to a lock or to a system pincode screen?]
Becuase you used find my I guess it is the system PIN code screen:
System lock PIN code
Your Mac asks for a PIN code when it has been remotely locked using Find My. Enter the four-digit or six-digit passcode to continue.
If your Mac boots to a lock symbol it means a firmware password is in place:
Lock icon
If your Mac is using a firmware password, the lock icon appears when you try to start up from another disk or volume, such as an external drive or macOS Recovery. Enter the firmware password to continue.
