Pressing "Square Root Intensity" in the Potential pane of STEM Simulation crashes the GUI

[sezelt]

I managed to build the v2.0.0 GUI on macOS, and also have figured out how to get the console output and debug info.

The error that I get when clicking on Square Root Intensity is below. I tried getting more info from the frame like the variables, but I get nothing (this is a Debug build)... Hopefully this is enough info to get an idea what's going wrong.
