Player crashes when disposing of a NativeArray

Core Runtime

Sep 09, 2022

Reproduction steps:
1. Open the attached project “IN-15295.zip”
2. Click Edit > Build And Run
3. Press “F” to engage in dialogue
4. Press “Space” repeatedly until the crash

Expected result: Build does not crash
Actual result: Build crashes

Reproducible with: 2021.3.9f1, 2022.1.16f1, 2022.2.0b7, 2023.1.0a10
Couldn't test with: 2020.3.38f1 (couldn’t downgrade because the scripts don’t support the older c# language version)

Reproducible on: Windows 10 Pro 21H2, MacOS 12.2.1 (Intel), macOS Monterey 12.5 (M1 Max), MacOS 12.5

Note: Lines 176-177 in “Assets/Scripts/UI/Dialog/DialogBubbleMeshSimulation.cs” causes the crash

Resolution Note:

This would report safety error in editor. Disposing copy of NativeArray will crash when job debugger is not present (i.e. in the player build).
Resolution Note (2023.1.X):

As working more on this issue, I think the condition in the StructureJob fails and makes the job system to write over the bounds of positions to velocities and corrupt it somehow. That's why it crashes when trying to dispose the velocities nativearray.
