Description

This issue was found from an external user on Twitter using UE5-Early Access - [Link Removed]

The crash happens on asset load.  User says that they were following Gabriele's video - [Link Removed]

I have also attached the original project zip UE5-Early Access project in question, which also produces the same error in UE5-EA and Release-5.0 - [Link Removed]

Steps to Reproduce
  • Download attached asset - [Link Removed]
  • Place asset in any project's content folder
  • Open project, locate the asset
  • Open the asset

Expected: Asset can be opened. Some warnings related to some soft references missing

Actual: Crash
