Training with Explainability + Edge results in Internal error

I am trying to train with Explainability of my data set training, however, if I run with this setting enabled + edge export, it always fails. I have tried 2 different data sets with the same outcome. If I remove the Explainability, it works fine. What is it about explainability enabled + edge that causes it to fail?

when I choose the “Generate Explainable Bitmap”, the UI has broken image links so maybe it’s related?

Thank you for any ideas. I see there is an issue tracker for this type of vague failure message but those can take a while to be prio’d
