Hello, when I run python3 api\index.py, I get this error

(DroneControl) C:\Users\Victus\anaconda3\envs\DroneControl\Mocap-Drones-main\computer_code>python api\index.py

I connected the esp32 to COM12 and made sure no other program is using the port. I have been trying to resolve this for two days now. can anyone help?

PermissionError(13, 'Access is denied.', None, 5)

Have you tried running with sudo? ie. sudo python3 api\index.py

Also make sure that your arduino ide / whatever you are using to program the ESP32 is closed, because it could also be connecting to the port.

I'm on windows. But I ran it as administrator. I also closed the arduino IDE but the error still persisted.

weird windows permission problem, I gave up windows and tried WSL, it worked.
