Reproduction steps:
1. Open the project attached by the user
2. Define "CRASH_BURST" in Scripting Define Symbols (Edit -> ProjectSettings -> Player -> Scripting Define Symbols)
3. Open Burst Inspector (Jobs -> Burst -> Open Inspector...)
4. In the search field type "MoveInputCancelSystem.ProcessCancels" and select it

Reproducible with: Burst 1.3.0-preview.5 (2019.3.7f1), 1.3.0-preview.8 (2019.3.7f1)
Not reproducible with: Burst 1.3.0-preview.9 (2019.3.7f1, 2019.3.11f1)

Notes:
- After upgrading to 1.3.0-preview.9 the issue might reproduce once, but after reopening the project won't reproduce anymore
- The issue seems to be caused by incorrect handling of variable casting to "uint" ((uint)someVariable)
