what problem?

No clue, the info you provide is way too little. Step 1 would be to decode the backtrace. Use addr2line or use the esp.py monitor function for that.

Flash Frequency: 40MHz
Flash mod: Dio
Flash size: 4MB
PSRAM: Disabled

This is the code:
#include "BluetoothSerial.h"

#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it
#endif

BluetoothSerial SerialBT;


void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
SerialBT.begin("ESP32P01");
pinMode(25, OUTPUT);

digitalWrite(25, HIGH); // LED Red
delay(500);
digitalWrite(25, LOW); // LED Red
delay(500);
digitalWrite(25, HIGH); // LED Red
delay(500);
digitalWrite(25, LOW); // LED Red
delay(500);

}

void loop() {
// put your main code here, to run repeatedly:
if (SerialBT.available()) {
char rxdata = SerialBT.read();
Serial.write(rxdata);
if (rxdata == '1') digitalWrite(25, !digitalRead(25));
}
}
