BoolVariable is a custom scriptable object that I have a custom property drawer for. I thought it might be responsible but the issue persists with it removed.

I should add I've since been able to get an exception thrown on occasion if I try to drag the input fields.

and I'm using the latest version, at least it was as of checking yesterday, of the mathematics package. "com.unity.mathematics": "1.0.0-preview.1",

 

I've submitted a bug report with a simpe project but I'll post the project here as well. (I'll add the bug report # when I get it.)
