Raspberry Pi OS - GPIO Pins configuration guide as Expected in Python Script

I'm trying to implement I recently switched to I'm currently working on a project using Raspberry Pi OS Bullseye and I'm having trouble with the GPIO pins not responding as expected in my Python script... I have installed the RPi.GPIO library, and I am trying to control an LED connected to GPIO pin 17. However, when I run my script, the LED doesn't turn on, and I don't see any behavior messages in the console. Here’s the code I am using: ```python import RPi.GPIO as GPIO import time # Set up GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(17, GPIO.OUT) # Turn on the LED GPIO.output(17, GPIO.HIGH) time.sleep(2) # Turn off the LED GPIO.output(17, GPIO.LOW) GPIO.cleanup() ``` I have confirmed that the LED is functional and correctly wired to the GPIO pin. Additionally, I have checked the permissions and I am running the script with `sudo`. I also tried adding a delay before `GPIO.output(17, GPIO.HIGH)` but it didn’t change the behavior. The strange thing is that if I run a simple command in the Python shell like `GPIO.output(17, GPIO.HIGH)`, the LED turns on immediately. This leads me to believe the scenario lies within the script execution context. Could there be a question with how the GPIO library is being initialized or a potential conflict with another process? Also, I have previously installed `gpiozero` for another project but have since uninstalled it. Could there be any lingering configuration issues? Any insights would be greatly appreciated! I'm working on a API that needs to handle this. I'd really appreciate any guidance on this. I'd be grateful for any help. The project is a service built with Python. I'm open to any suggestions.
