Resolution Note:
This is a limitation of il2cpp (.Net Framework and CoreCLR). At code generation time and at runtime il2cpp processes instance and static fields at the same time. Your case creates a circular dependency between `Result` and the inflated `UniTask<Result>`.
We do not plan to fix this in il2cpp as CoreCLR also does not handle this case and we are in the process of adding CoreCLR support to the Unity Player.
If Microsoft decides to fix this issue we will re-evaluate the bug for il2cpp.
