Shader issues running in Unity 2021

[dev-bre]

Hi, I just cloned the repo and tried to run the game, I am getting thousands of shader errors (see Issue 6 which highlights that already) and also this additional type of error:

ArgumentException: AsyncGPUReadback cannot use Temp memory as input since the result may only become available at an unspecified point in the future.
UnityEngine.Rendering.AsyncRequestNativeArrayData.CreateAndCheckAccess[T] (Unity.Collections.NativeArray`1[T] array) (at <f1212ad1dec44ce7b7147976b91869c3>:0)

Do you have any plans on fixing the project and make it work in latest Unity versions?

Any update on this matter?

the specific AsyncGPUReadback problem is a unity bug ; use build v 2020.3.26f1 or later
