ImmersiveVRTools.Common.Runtime: UnityMainThreadDispatcher can't be initialized on worker thread

Just got hit by an exception where code tried to get the `.gameObject` property from a worker thread. It was during `SafeInvoke(HotReloadFailed, changesAwaitingHotReload);` triggering `ProjectWindowReloadStatusIndicatorDrawer.OnHotReloadFailed` which in turn accesses `UnityMainThreadDispatcher.Instance` which in `SingletonBase` will try to access stuff that should only be accessed on the main thread in case there is no singleton instance. Sorry for oral account of the callstack but my debugger got detached when I was poking around and CBA to repro. 😅

Anyway, maybe the main thread dispatcher needs to eaglery be inited from the main thread (RuntimeInitializeOnLoad?) if its means to be accessed from a worker, or just use another singleton implementation that doesn't hit Unity's API.

Commencez par la chaîne d’appels signalée depuis SafeInvoke(HotReloadFailed, changesAwaitingHotReload), en passant par ProjectWindowReloadStatusIndicatorDrawer.OnHotReloadFailed, UnityMainThreadDispatcher.Instance et SingletonBase. Déterminez quel chemin d’initialisation accède aux Unity APIs depuis le thread worker. C’est terminé lorsque l’échec de hot-reload signalé ne déclenche plus d’exception d’Unity API depuis un thread worker et que le comportement concerné a été vérifié dans Unity.
