Hi Jennifer!
I'm so sorry for the trouble! This is a bug that our team has recently discovered, too, and we are currently looking into it.
I don't have a specific timeline to share, but I did find a workaround that might be helpful in the meantime. We recommend opening Action Fine Tuning from Story View instead of opening it within the slide to prevent Storyline from crashing.
We'll keep you updated on the progress of this bug in this discussion!
Thank you. With the work around, it did crash some but not every time like before.
