[WebGL][Bolt] "Failed to deserialize scriptable object" error is thrown when launching WebGL Player built with Bolt
How to reproduce:
1. Open the attached project
2. Make a WebGL Build
3. Open the built WebGL Player on a browser
4. Open the Developer Console (shortcut F12)
5. Inspect the Console
Expected result: Scriptable Objects are deserialized successfully
Actual result: "Failed to deserialize scriptable object" error is thrown
Reproducible with: 2019.4.21f1, 2020.2.7f1, 2021.1.0b9, 2021.2.0a7

- Redoing creation of Sub Scenes and Cube GameObjects in Hierarchy throws “Assertion failed on expression: 'targetScene != nullptr’” error in Console window
- Selecting “New Sub Scene” after assigning “New Scene” in Sub Scene Script Component throws “Destroying GameObjects immediately is not permitted” in the Console window
- Shader Graph "Zoom Step Size" can be set to 0 even though the zoom still works
- Enabling/Disabling the Deprecated Nodes doesn't apply to the opened Shader Graph unless any Variable is added to the Blackboard
- Group Selection title text size is smaller in renaming than the actual font size
Resolution Note:
The issue is fixed if an "AOT Pre-Build" (Tools -> Bolt -> AOT Pre-Build) is started before the project is built. This is not a bug. Unity 2021 and onwards don't support Bolt and use VisualScripting instead. VisualScripting automatically runs the "AOT Pre-Build" when a project is built.
