Resolution Note:
Hi,
The reason this issue occurs is because the StyleSheets are loaded in too early as a consequence of the InitializeOnLoad attribute in GlobalToolbarHiding.cs.
Unfortunately we do not support asset loading for InitializeOnLoad because it can lead to problems.
You can find out more about it in the documentation here:
https://docs.unity3d.com/ScriptReference/InitializeOnLoadAttribute.html
As a workaround, AssetPostprocessor.OnPostProcessAllAssets can be used to achieve a similar effect.
