Summary0004798: [Unreal] Crash when adding items to a sample data collection
Description

Repro steps:

  • Create a viewmodel struct, adding a collection of strings
  • Add items to it in the sample data
  • If there's only one item, pressing enter or tab seems to crash the editor.
  • if we pre-create items, the moment we add one character to the first one, the editor crashes (screenshot 1)

I'm attaching whatever debug info I can and the sample data.
