if you are using Arduino IDE, you can try platformio, it feels like Arduino IDE's problem.

Esp32's core files have been modified with 3.0.0, so there is an incompatibility. The workaround is to revert to version 2.0.17 until the library developers bring an update.

That's all you need to do:
1, Open BleKeyBoard.ccp in the ESP32_BLE_Keyboard lib
2, change "hid->manufacturer()->setValue(deviceManufacturer);" TO "hid->manufacturer()->setValue(String(deviceManufacturer.c_str()));"

3, change "BLEDevice::init(deviceName);" TO "BLEDevice::init(String(deviceName.c_str()));"
Run it again.

amazing. thank you
