Lost Newbie has Returned: ArUco Detection Edition

Oh wait! Before you do, this was not the error I was expecting. We actually managed to call the constructor, we just gave it bad configurations. I googled the error and this came up.

In the latest release all the xxx_configuration methods were renamed to to create_xxx_configuration.
So you need to call create_preview_configuration() as in the updated example here:
picamera2/examples/preview.py at main · raspberrypi/picamera2 · GitHub

Maybe I was supposed to use:

config = picam2.create_preview_configuration({"size": (640, 480)})

Wanna try that first?
How did you go listing out your installed packages using pip list and grep
