INPUT_SHAPE_CALIBRATION overloading system memory and crashing klipper

[pwilliams105]

Hi Mate,
Absoloutly love your work mate! you are a wizard!
I have a question in relation to the above title. Every time I run the calibration, everything works as it should, then it gets right to the end when I need to SAVE_CONFIG, and it crashes, I noticed at that point the system memory spikes all the way to 100%, and it crashes.
I have tried a full factory reset, installing just this macro and nothing else to lower system loads but still crashes. Cleared cache, logs, etc (could be more i need to do, I'm definitely not great at coding but learning slowly)
Ive tried restarting Klipper multiple times and still nothing.
Any help would be greatly appreciated.
