Reproduction steps:
1. Create a new project
2. Enable GPU resident drawer on the SRP asset in use
3. Install ProBuilder package (Window Package Management > Package Manager > Unity Registry > ProBuilder) (ProBuilder tested on version 6.0.9)
4. Click on “Create Cube” Tool in the Scene window
5. Click and drag in the Scene window to create a cube
6. Observe the Console

Actual result: “InvalidOperationException: Types UnityEngine.EntityId and System.Int32 are different sizes - direct reinterpretation is not possible…” error and warnings are thrown
Expected result: No errors or warnings are thrown

Reproducible with:  6000.5.0b1, 6000.5.0b9, 6000.6.0a5
Not reproducible with: 6000.4.8f1, 6000.5.0a9

Reproduced on: Windows 11, macOS Tahoe 26.4 (M4)

To Debug, run app with -diag-job-temp-memory-leak-validation cmd line argument. This will output the callstacks of the leaked allocations. {code}
