[error] Can't burn bootloader! --> esptool.py v2.0

Hi, I’m an Unisa student, i was writing my project’s code when “impossible to open serial COM5”. I tried to forget all devices, disambiguate again mine and register a new virtual machine. Now when i try to do last operation it appears “[error] Can’t burn bootloader! --> esptool.py v2.0” followed by
““serialwin32.py”, line 66, in open
raise SerialException(“could not open port %r: %r” % (self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port ‘COM5’: PermissionError(13, ‘Accesso negato.’, None, 5)”
All worked for me until yesterday

Hi @simo51298
This error could be due to different reasons, for instance, is there any other program that is communicating with the device?
In your OS, Could you recognize the device correctly? Could you open a serial terminal application like Putty with your device?
