How to reproduce:
1. Create and open a new project
2. In the Hierarchy, right-click and create a 3D cube (3D Object -> Cube)
3. In the Inspector, add a Rigidbody component
4. Drag the cube from the Hierarchy to the Project window to make a Prefab
5. Select the Prefab and change any of the values of the Rigidbody in the Inspector to any arbitrary value (e.g. change "Mass" to 2, or tick/untick constraints)
6. Enter and exit Play mode
7. Repeat steps 5-6 until it crashes

Reproducible with: 6000.3.7f1, 6000.3.10f1, 6000.4.0b10, 6000.5.0a7
Not reproducible with: 6000.0.68f1, 6000.3.6f1

Reproducible on: Windows 11
Not reproducible on: macOS 15.7.2 (M1 Max) (Metal)

Notes:
-The repro steps are not consistent and may require multiple attempts until a crash occurs.
-This crash is easier to reproduce after the first time it occurs. For example, reproducing the crash on 6000.3.7f1 might take multiple attempts, however subsequently attempting to reproduce the crash on 6000.4.0b10 (or even the same version) might only require a few changes to the Rigidbody component and starting Play mode for it to occur.
