Hi everyone, I just got a raspberry pi 5 and what I noticed right away was how to use the GPIO. With RPI4 it's a lot easier, and with this one I've had a lot of problems. The GPIO control library is not the same, and so far I've only been able to do it with gpiozero. Even with the use of this library for such a simple program to check if I pressed a push button gives me an error. Below I show the simple test code I have and the error I am presented with.
THE CODE:

PS: I tried with different pins and it gives me the same error. At the first attempt it ran well. Hope that someone can help me with this one
