That'll be why the I2C freezes, I believe you have Gen2 so you will need an I2C buffer. You can also try shortening the wires from the shield to controller on SCL and SDA pins. Right now the signal is on the edge.
You're the 3rd person to mention calibration for pH takes a long time but it's ok. This actually makes me happy because it appears my pH circuit is more stable than Atlas. When I made the auto-cal mode I used my circuit, in order to pass the calibration point the reading needs to stay within +/- .004 for 60 seconds, otherwise the timer will restart so it is a high standard. As an example if it read 7.012 and 60 seconds or less it was 7.017 it won't pass. When my circuit picks a number it stays within this range pretty easy and can pass the test without issue. You likely have to wait 10 minutes as that's when the step completely times out. I will have to put a note saying it will exit after 10 minutes as it can feel like it will never end.
