The tests in this project pass in full using Unity 2020.2.3f1. If the project is opened with 2021.1.0b3 all the tests fail and spew NativeArray and lighting2D URP errors to the console. Looks like the errors are related to 2D URP lighting. Let me know if this is not the case.

Steps to reproduce
- git clone git@github.cds.internal.unity3d.com:unity/internal-perfect-pixel-adventures.git -b 2020.2
- Open the project in Unity 2021.1.0b3
- Open the test runner
- Run all tests
Notice Issue >> Test runner reports all tests fail. Numerous errors are spewed to the log.

Tested Platform: macOS 11.1
Reproduced on Unity 2021.1.0b3, 2021.1.0b1
Working on Unity 2020.2.0b3, 2021.1.0a1
