This occurred under Unity 2018.2.14 using Plugin 2.1.
The attached crash report shows it occurring at:
Substance.Engine.dll caused an Access Violation (0xc0000005)
in module Substance.Engine.dll at 0033:558d24e8.
The line of code in my project it's apparently complaining about is:
DecalGraph.SetInputString("Text", Text);
This is being called in OnValidate in the Editor. However, the same crash occurs if I call this via a simple Inspector button after having previously just modified and Apply'd the SBSAR.
It doesn't seem to matter what input I set. This is the stack trace when I try to set a Float instead:
C++ Error in InsertNumericValuesIntoArray(), invalid Substance input identifier: 'Font_Size'!

Even though it claims it is complaining about a property "Font_Size", that property definitely exists in my Graph, and this method work properly as long as I haven't just Apply'd the graph in the inspector.
More on this. Here's some code I'm calling in a script to display the properties of the graph:
var sb = new StringBuilder();
foreach (var prop in myGraph.GetInputProperties())
{
sb.AppendLine($"Prop: {prop.name} - {prop.type}");
}
Debug.Log($"Properties: {sb.ToString()}");If I open Unity fresh, and call this method via a button in the Inpsector, I get the full list of all properties of the graph. If I then edit the graph and press Apply, then call this again, I get an empty list.
So what's going on when pressing Apply that causes so many values to be missing? The only way I can "Fix" the graph is to enter Play mode and then exit. Then I can iterate over the list of graph properties again. Even then, some of the time, when doing that, I get this error in my console:
