It looks like you might already have an overlay loaded that uses the ADC, so PyBBIO is unable to configure it the way it needs.
Post the output of # cat /sys/devices/bone_capemgr.*/slots
Also, reboot and run that same script, then right afterwards get the output of # dmesg and post that (or a pastebin of that).

Bingo!!
Your comment led me to the conclusion that the Adafruit ADC is executed in a python script as part of the startup. When removing this from the boot sequence, your script executes fine.
So thanks a lot for the pointer. I would not have located the error without it!!!
