Crash with multiple stack traces when using specific Model Asset

How to reproduce:
1. Open the attached “AGENTAS.zip” project
2. Open the “SampleScene”
3. Enter Play mode
4. Observe the crash

Reproducible with: 4.0.0 (6000.0.78f1), 4.0.3 (6000.0.78f1, 6000.5.1f1)
Not reproducible with: 2.3.0-exp.3 (6000.0.78f1, 6000.5.1f1), 4.0.3 (6000.6.0b1, 6000.7.0a1)
Could not test with: 3.0.0 (6000.0.78f1, 6000.5.1f1)

Reproduced on: macOS 26.5.1 (25F80) (M3 Max)
Not reproduced on: No other environment tested

Note: The crash may require entering Play mode 2-3 times before it occurs
