The "Preloaded Assets" from Player Settings do not always get preloaded when entering Play mode in Editor

Build Pipeline

-

Feb 19, 2020

How to reproduce:
1. Open 'Scene' from "PreloadedAssetsInit.zip"
2. Start Play mode
3. Inspect the text line in Game window

Expected result: Text is "Loaded correctly"
Actual result: Text is "Not loaded"

Reproducible with: 2017.4.37f1, 2018.4.19f1, 2019.3.5f1, 2020.1.0b1, 2020.2.0a2

Notes:
1. The ScriptableObject gets loaded and its OnEnable() called as expected in Editor after selecting it from Project window or opening Player settings window.
2. Need to open project normally to reproduce. Might not reproduce right after project upgrage/downgrade.

Resolution Note:

https://docs.unity3d.com/ScriptReference/PlayerSettings.GetPreloadedAssets.html
Per documentation, preloaded assets are only loaded as part of the player startup sequence, not editor play mode as those are different things.

Hmmm… I feel the same about "by design". If you're here, because you want to get ScriptableObjects enabled in the editor w/o the need to manually load or reference them in some way, here's my workaround: https://forum.unity.com/threads/how-does-preloaded-assets-in-player-settings-work.318259/#post-7086490

The documentation is completely unclear on this point and should offer an example of how to best manage it in Editor if it is a feature that is used. Closing this as "By Design" is extremely frustrating.
