Adding Array Item Crashes UEFN?!?

Summary

When I add an array item to my creative_device it crashes when I try to add a 3rd item. Adding 2 is fine, but when I click the + button to add a 3rd element UEFN fully crashes and gives me the shown crash report.

I was having the same issue, though I was able to track down the cause of this.
I had a “Sequences” array inside of another “Sequences” array. By renaming the inner array to something else like “Instances” I was able to prevent the editor from crashing. This issue appears to be tied to naming conventions.

I had an array called “Components” inside of an Array called “Components” aswell.
