InvalidOperationException: Target playerLoopTiming is not injected

[crisdesivo]

When using UniTask in Unity 2022.3.41.f1 for WebGL export I get the following error:

InvalidOperationException: Target playerLoopTiming is not injected. Please check PlayerLoopHelper.Initialize. PlayerLoopTiming:Update
  at Cysharp.Threading.Tasks.PlayerLoopHelper.ThrowInvalidLoopTiming (Cysharp.Threading.Tasks.PlayerLoopTiming playerLoopTiming) [0x00000] in <00000000000000000000000000000000>:0 
--- End of stack trace from previous location where exception was thrown ---

I added await UniTask.Yield(PlayerLoopTiming.Initialization); before starting the UniTask and it never proceeds.

It works without any issue for Windows/Linux export and also in the editor.

There are occasional reports of automatic injection not working in WebGL.
While the exact details are unclear...
As a workaround, I think it would work if you explicitly call Initialize before your product code.

var playerLoop = PlayerLoop.GetCurrentPlayerLoop();
PlayerLoopHelper.Initialize(ref playerLoop);
