Crash while trying to import a C4D file with Animation via Datasmith

Description

The file was originally created by Mixamo and saved as FBX. It was resaved it in C4D with the Save for Cineware Option. Importing it into the Editor causes it to crash.

This was tested and reported in 4.24.3 (CL-11590370). this was reproduced in 4.25 Preview 4 (CL-12366721), and Main 4.26 (CL-12689888)

Steps to Reproduce
  1. Open the UE4 Editor and create a Blank Project with Datasmith enabled
  2. Enable Cinema 4D importer if it isn't already
  3. Extract the attached file and import it into the Editor

Results: The Editor crashes

Expected: The Editor doesn't crash and import is successful
