The device is too cold to charge

Charging is stopped when the charger is inserted because the temperature is too low. is displayed and charging is not possible. I replaced the NFC coil, main board and sub board, and charging port, but it didn't improve. Also, when the sub-display is attached, it freezes at the startup logo and cannot be started, but when it is removed, it can be started normally. Which component do you suspect is defective?
