2. Add the {{com.unity.cloud.gltfast}}package through Package Manager
3. Download the “user’s attached 3D model file”
4. Drop the file into the Project window
5. Observe the crash

Reproducible with: 6.10.3, 6.11.0, 6.12.0 (6000.1.5f1), 6.12.1 (2021.3.52f1, 2022.3.62f1, 6000.0.50f1, 6000.1.5f1, 6000.2.0b4)
