Project hangs when QualitySettings.vSyncCount is set to 0 after invoking Screen.SetResolution method in a coroutine

Unity: Scene View

Won't Fix

2023.1.X

2022.1.X

2021.3.X

2020.3.X

Issue is caused by the Cyriaca package, not the Unity Editor. Specifically, the GetInitEnumerator() function which is defined by the package causes a short hang in the editor regardless of whether there are any calls to SetResolution or Vsync settings.

How to reproduce:
1. Open the user's attached "MinRepro" project
2. Enter the Play Mode in the "TestScene" Scene

Expected result: The cube in the Scene is spinning without any interruption
Actual result: After a few seconds after entering the Play Mode, the project freezes for a few seconds

Reproducible with: 2020.3.34f1, 2021.3.2f1, 2022.1.0f1
Couldn't test with: 2019.4.39f1 (downgrading errors are thrown), 2022.2.0a13 (project crashes at entering the Play Mode)

Reproduced on: MacOS 12.3 (Intel)
