    This happens on all 2021 versions past 0.32 & we can't use versions prior to that as it has the webrequests take 3-5x longer issue. 2021 LTS is looking fairly bad

    Getting "Cannot create web request without initializing the system" in Windows, Mono, 2022.3.26f1.

    Is there a recommended way to detect we shouldn't schedule UnityWebRequest because application is quiting?
