This code is from the original Overview | Kitty Toe Bean Keypad with Color TFT | Adafruit Learning System, with modifications for setting up the SPI interface. The appears to be a bug in CircuitPython, it is being worked on. It works fine when all the code for the TFT is commented out. It works fine when all the Keyboard stuff is commented out but give an error when both are configured:
