```

Start with the reported Windows 11 command and inspect flash_program.py and flash_program_ll.py, especially burn_bin_files where serialport.open() fails for COM3. Reproduce the firmware flashing attempt with the listed HaaS Edu K1 firmware and port. Done means the tool can open the selected serial port and proceed without the reported PermissionError.
